| 1 | Reactivation of γ-globin expression through Cas9 or base editor to treat β-hemoglobinopathies显示文摘Dear Editor,Mutations in the β-globin gene,the essential component of adult hemoglobin(HbA;a2p2),results in either a production of aberrant sickle hemoglobin(HbS)leading to sickle cell disease(SCD)or an insufficient β-globin synthesis leading to β-thalassemia.These two major forms of β-hemoglobinopathies cause impaired erythropoiesis and life-threatening anemia.Clinical evidence has suggested that reaaivation of fetal γ-globin(HBG)gene expression which is normally silenced after birth by certain genetic mutations can ameliorate the clinical course of β-hemoglobinopathies. | Liren Wang Linxi Li Yanlin Ma Handan Hu Qi Li Yang Yang Wenbang Liu Shuming Yin Wei Li Bin Fu Ryo Kurita Yukio Nakamura Mingyao Liu Yongrong Lai Dali Li | 2020 | Cell Research2020，30，3： | 14 |

| 3 | Measurement of the fluidized velocity in gas-solid fluidized beds based on AE signal analysis by wavelet packet transform显示文摘An energy distribution theory was presented based on regular evolvement of energy fraction of acous-tic signals with fluidization velocity. Wavelet packet analysis was used in processing the acoustic sig-nals originated from particle impact on the wall of a fluidized bed. A new criterion of judging incipient fluidization(Umf) velocity and minimum turbulent velocity(Umt) was proposed according to the energy distribution theory. Experiments were performed with five groups of high density polyethylene(PE) particles and one bimodal PE to acquire incipient fluidization velocity and minimum turbulent velocity by using the criterion. The feasibility of this method in obtaining characteristic fluidization parameters was further verified by comparing it to results from the pressure drop method and the empirical value from industry. | WANG JingDai YANG YongRong GE PengFei SHU WeiJie HOU LinXi | 2007 | Science China Chemistry2007，50，2： | 8 |
| 4 | Ethanol disrupts the formation of hypochord and dorsal aorta during the development of embryonic zebrafish显示文摘Exposure to ethanol during human embryonic period has severe teratogenic effects on the cardiovascular system. In our study, we demonstrated that ethanol of gradient concentra-tions can interfere with the establishment of circulatory system in embryonic zebrafish. The ef-fective concentration to cause 50% malformations (EC50) was 182.5 mmol/L. The ethanol pulse exposure experiment displayed that dome stage during embryogenesis is the sensitive time window to ethanol. It is found that 400 mmol/L ethanol pulse exposure can induce circulatory defects in 43% treated embryos. We ruled out the possibility that ethanol can interfere with the process of hematopoiesis in zebrafish. By employing in situ hybridization with endothelial bio-marker (Flk-1), we revealed that ethanol disrupts the establishment of trunk axial vasculature, but has no effect on cranial vessels. Combined with the results of semi-thin histological sections, the in situ hybridization experiments with arterial and venous biomarkers (ephrinB2, ephB4) sug-gested that ethanol mainly interrupts the development of dorsal aorta while has little effect on axial vein. Further study indicated the negative influence of ethanol on the development of hy-pochord in zebrafish. The consequent lack of vasculogenic factors including Radar and Ang-1 partly explains the defects in formation and integrity of dorsal aorta. These results provide im-portant clues to the study of adverse effects of ethanol on the cardiovascular development in human fetus. | QIAN Linxi WANG Yuexiang JIANG Qiu ZHONG Tao SONG Houyan | 2005 | Science China(Life Sciences)2005，48，6： | 6 |
| 5 | Photodeposition of CoOx and MoS2 on CdS as dual cocatalysts for photocatalytic H2 production显示文摘Photocatalytic Hproduction from water splitting has a promising prospect for alleviating energy and environmental issues.However,the fast recombination of photogenerated charge carriers limits the photocatalytic efficiency and its practical application.Cocatalyst engineering is an effective strategy to spatially separate photogenerated charge carriers.In this work,noble-metal-free MoSand CoOcocatalysts are loaded on CdS nanorods by a two-step photodeposition method.The MoSfunctions as the reduction cocatalyst to trap electrons and Co Oas the oxidation cocatalyst to trap holes.Transmission electron microscopy(TEM),inductively coupled plasma(ICP),X-ray photoelectron spectroscopy(XPS)and MottSchottky results demonstrate the effectiveness of photodeposition for loading MoSand CoOdual cocatalysts on CdS and their impact on the photochemical properties.The optimized CdS-MoS-CoOcomposite exhibits a high photocatalytic H-production rate of 7.4 mmol g^(-1)h^(-1)and an apparent quantum efficiency(QE)of 7.6%at 420 nm.Further analysis on time-resolved photoluminescence(TRPL)indicates that the introduction of dual cocatalysts greatly prolongs the lifetime of photogenerated charge carriers and deceases the charge recombination rates,consequently leading to superior photocatalytic H-production performance.This work provides a facile and effective strategy for the construction of highly efficient dual-cocatalyst-modified CdS photocatalyst for high-performance photocatalytic Hproduction. | Tingmin Di Quanrong Deng Geming Wang Shenggao Wang Linxi Wang Yuhua Ma | 2022 | Journal of Materials Science & Technology2022，，29： | 5 |
| 6 | Review on g-C_(3)N_(4)-based S-scheme heterojunction photocatalysts显示文摘With the rapid development of economy and modern industry,serious environmental pollution and energy shortage have become major urgent challenges to the human society.Photocatalysis is a promising technology to provide green energy.As a typical metal-free polymer photocatalyst,g-C_(3)N_(4) has attracted more and more attention due to its excellent performance.Unfortunately,the fast recombination of photo-induced charges,limited light response range as well as weak oxidation ability are still the key drawback that restrict the photocatalytic performance of g-C_(3)N_(4).These problems can be effectively addressed by constructing g-C_(3)N_(4)-based heterojunctions with two or more semiconductor materials,during which the respective advantages can be integrated.Up to now,the various oxidation semiconductor photocatalysts have been tried to construct the novel S-scheme heterojunction photocatalysts with g-C_(3)N_(4).Thus,this review provides a comprehensive introduction of g-C_(3)N_(4)-based S-scheme heterojunctions,including the main characteristics of the S-scheme heterojunction,photocatalytic mechanisms,design rules and preparation methods of g-C_(3)N_(4)-based S-scheme heterojunction photocatalysts.Moreover,this review summarizes recently reported works on the potential applications of g-C_(3)N_(4)-based S-scheme photocatalysts in various important photocatalytic reactions,including photocatalytic hydrogen production,photocatalytic degradation of contaminants,photo-reduction of CO_(2) into fuels,and photocatalytic sterilization.Finally,based on the current research progress,we propose some shortages in the preparation methods and applications of g-C_(3)N_(4)-based S-scheme heterojunctions,which are to be further investigated and resolved in this promising and creative research field. | Yunfeng Li Zhiling Xia Qing Yang Linxi Wang Yan Xing | 2022 | Journal of Materials Science & Technology2022，，30： | 5 |
| 7 | Holocene climate change and anthropogenic activity records in Svalbard: a unique perspective based on Chinese research from Ny-?lesund显示文摘Climate change in the Arctic region is more rapid than that in other areas owing to Arctic amplification.To better understand climate change and the driving mechanisms,long-term historical reconstructions throughout the Holocene and high-resolution records of the past few hundred years are required.Intense anthropogenic activities in the Arctic have had a great impact on the local environment.Here,we review the Holocene climate change record,responses of the ecosystems to climate change,and the anthropogenic impacts on the environment based mainly on Chinese research from Ny-?lesund.Climate reconstruction studies from Svalbard have revealed several cold episodes during the Holocene,which are consistent with ice rafting events in the North Atlantic region and glacier activity from Greenland,Iceland,and Svalbard.The ecosystem also showed corresponding responses to climate change,especially during the late Holocene.Over recent decades,anthropogenic activities have caused serious pollution and deterioration to the local environment in Svalbard in areas frequented by people.Greater environmental protection is therefore needed to reduce the anthropogenic impacts on the local environment. | YANG Zhongkang YUAN Linxi WANG Yuhong SUN Liguang | 2017 | Advances in Polar Science2017，28，2： | 2 |
| 8 | Surface patterning and modification of polyurethane biomaterials using silsesquioxane-gelatin additives for improved endothelial affinity显示文摘Polyurethanes(PUs) are well-known for their biocompatibility but their intrinsic inert property hampers cell-matrix interactions. Surface modifications are thus necessary to widen their use for biomedical applications. In this work, surface modifications of PU were achieved first by incorporating polyhedral oligomeric silsesquioxane(POSS), followed by alteration of the surface topography via the breath figures method. Subsequently, surface chemistry was also modified by immobilization of gelatin molecules through grafting, for the enhancement of the surface cytocompatibility. Scanning electron microscopy(SEM) was used to verify the formation of highly ordered microstructures while static contact angle, FTIR and XPS confirmed the successful grafting of gelatin molecules onto the surfaces. In vitro culture of human umbilical vein endothelial cells(HUVECs) revealed that endothelial cell adhesion and proliferation were significantly enhanced on the gelatin-modified surfaces, as shown by live/dead staining and WST-1 proliferation assay. The results indicated that the combination of the strategies yielded an interface that improves cell attachment and subsequent growth. This enhancement is important for the development of higher quality biomedical implants such as vascular grafts. | HOU LinXi PECK Yvonne WANG XiaoWen WANG DongAn | 2014 | Science China Chemistry2014，57，4： | 2 |
| 9 | Evaluation of the toxicity of fluorine in Antarctic krill on soft tissues of Wistar rats显示文摘Antarctic krill are a potential food source for humans and animals, but krill are known to contain high levels of fluorine (F). In this study, we investigated the toxicity of F in Antarctic krill using Wistar rats. There were three experimental groups: The control group were fed a basal diet, the krill treatment group were fed the same basal diet mixed with krill powder (150 mg·kg-1 F), and the sodium fluoride (NaF) treatment group were fed the basal diet with added NaF (150 mg·kg-1 F). General toxicity indicators including body weight and food intake were measured during the experiment. After three months the rats were dissected and tissue samples were collected from the liver, kidney, spleen, brain, and testis. Morphological changes in the cells of these tissues were assessed using HE staining. There were no significant differences in the body weight, the food intake, or the viscera coefficients among the three groups. In both treatment groups some pathological changes were observed in all soft tissue samples except the testis, although there were fewer and less severe pathological changes in the krill treatment group than in the NaF treatment group. The results showed that the toxicity of F in Antarctic krill was lower than for an equivalent amount of F in NaF, but it was still toxic to rats consuming large quantities of krill. The findings of this study highlight the need for further investigation into potential F toxicity if krill is to be used for human consumption. | ZHANG Ling LU Xiaoqi WANG Zhangmin QIN Liqiang YUAN Linxi YIN Xuebin | 2013 | Advances in Polar Science2013，24，2： | 2 |
| 10 | Characterization of Fe-S minerals influenced by buried ancient woods in the intertidal zone,East China Sea显示文摘An ancient wood layer dated at about 5600 cal. a BP by AMS14C dating was discovered in the intertidal zone, East China Sea. Samples affected by ancient woods, including fresh coast bedrock, weathering bedrock, seepage water from coast, seepage water from ancient wood layer, intertidal seawater, fresh water, beach mud, ancient wood barks and ancient peat, were collected for geochemical analysis. The beach mud and the bacteriogenic iron oxides (BIOS) in coastal seepage water were analyzed by min-eralogical and high-resolution transmission electron microscopy (HRTEM)-selected area electron dif-fraction (SAED) analysis. Inorganic sulfur compositions and δ34S of the ancient peat and the beach mud were determined. The results showed that Fe, Mn, S (SO42-) were enriched in the intertidal area at different levels, very likely caused by fermentation of ancient woods. The presence of abundant iron-oxidizing bacteria (FeOB) and sulfate-reducing bacteria (SRB) in this intertidal zone was confirmed by HRTEM-SAED observation, and these bacteria were involved in Fe-S cycle to induce extracellular biomineralization. The negative δ34SV-CDT (-2.9‰) likely indicated the biogenic origin of iron-sulfide minerals in the beach mud at high sulfate reduction rate (SRR). These findings are helpful for under-standing the biogeochemical Fe-S cycle and biomineralization process at high organic matter deposition rate and high SRR in the intertidal zone, estuary, or near shoreline. | YUAN LinXi SUN LiGuang FORTIN Danielle WANG YuHong WU ZiJun YIN XueBin | 2009 | Chinese Science Bulletin2009，54，11： | 1 |
| 11 | 3D ordered macroporous sulfur-doped g-C_(3)N_(4)/TiO_(2)S-scheme photocatalysts for efficient H_(2)O_(2)production in pure water显示文摘Photocatalytic hydrogen peroxide(H_(2)O_(2))production offers a clean and cost-efficient alternative to the traditional anthraquinone oxidation approach.Herein,a step-scheme(S-scheme)heterojunction photocat-alyst is fabricated by coupling TiO_(2)with three dimensionally ordered macroporous sulfur-doped graphitic carbon nitride(3DOM SCN/T)by electrostatic self-assembly.The optimized photocatalyst achieved a high photocatalytic H_(2)O_(2)production activity with a yield of 2128μmol h^(−1)g^(−1)without the addition of hole scavengers.The remarkable performance was attributed to the synergy between the 3DOM framework and the S-scheme heterojunction.The former enhances light harvesting and provides abundant active sites for surface reactions,while the latter promotes the spatial separation of photogenerated carriers and enhances the redox power.Finally,the mechanism of photocatalytic H_(2)O_(2)production over the 3DOM SCN/T S-scheme composite is proposed.This work provides novel insights into the development of effi-cient photocatalysts for H_(2)O_(2)production from water and O_(2). | Zicong Jiang Qing Long Bei Cheng Rongan He Linxi Wang | 2023 | Journal of Materials Science & Technology2023，，31： | 1 |
| 12 | Evaluation of the biological toxicity of fluorine in Antarctic krill显示文摘Antarctic krill is a potentially nutritious food source for humans, but fluorine(F) toxicity is a matter of concern. To evaluate the toxicity of F in Antarctic krill, 30 Wistar rats were divided into three groups with different dietary regimens: a control group, a krill treatment group(150 mg·kg-1 F), and a sodium fluoride(NaF) treatment group(150 mg·kg-1 F). After three months, F concentrations in feces, plasma, and bone were determined, and the degree of dental and skeletal fluorosis was assessed. The F concentrations in plasma and bone from the krill treatment group were 0.167 0±0.020 4 mg.L-1 and 2 709.8±301.9 mg·kg-1, respectively, compared with 0.043 8±0.005 5 mg·L-1 and 442.4±60.7 mg·kg-1, respectively, in samples from the control group. Concentrations of F in plasma and bone in the krill treatment group were higher than in the control group, but lower than in the NaF treatment group. The degree of dental fluorosis in the krill treatment group was moderate, compared with severe in the NaF treatment group and normal in the control group. The degree of skeletal fluorosis did not change significantly in any group. These results showed that the toxicity of F in Antarctic krill was lower than for an equivalent concentration of F in NaF, but it was toxic for rats consuming krill in large quantities. To conclude, we discuss possible reasons for the reduced toxicity of F in Antarctic krill. The present study provides a direct toxicological reference for the consideration of Antarctic krill for human consumption. | ZHANG Ling LU Xiaoqi WANG Zhangmin QIN Liqiang LIN Zhiqin YUAN Linxi ZHANG Wen YIN Xuebin | 2014 | Advances in Polar Science2014，25，1： | 1 |
| 13 | S-scheme ZnO/WO3 heterojunction photocatalyst for efficient H2O2 production显示文摘Designing highly efficient photocatalyst for hydrogen peroxide(HO)production is an ideal strategy to avoid the shortcomings of traditional HOproduction and to realize the conversion of solar energy to chemical energy.In this work,a step-scheme(S-scheme)heterojunction photocatalyst composed of Zn O and WOis carefully prepared by hydrothermal and calcination method for efficient photocatalytic HOproduction.The ZW30 composite photocatalysts exhibit enhanced activity with the highest HO-production rate of 6788μmol Lh.The results show that the photocatalytic HOproduction process is dominated by a direct two-electron Oreduction pathway.The enhanced photocatalytic HO-production activity is attributed to the formation of interfacial internal electric field(IEF)in the S-scheme heterojunction,which boosts the spatial separation of charge carriers and enables electrons with the strongest reduction power to participate in HOproduction.This work provides an in-depth insight of the great advantages of S-scheme heterojunction in photocatalytic HOproduction. | Zicong Jiang Bei Cheng Yong Zhang S.Wageh Ahmed A.Al-Ghamdi Jiaguo Yu Linxi Wang | 2022 | Journal of Materials Science & Technology2022，，29： | 1 |
| 14 | Iron-mediated lysosomal-mitochondrial crosstalk:a new direction in the treatment of aging and aging-related diseases显示文摘A recent study by Hughes et al.[1]showed that cysteine-mediated iron deficiency is the main cause of aging-related mitochondrial dysfunction.They also uncovered that aging-induced vacuolar/lysosomal de-acidification participates in the cysteine-mediated iron deficiency,implying that the de-acidifying lysosome triggers vacuolar/lysosomal dysfunction and iron deficiency,further leading to mitochondrial dysfunction.Previous studies showed that iron and lysosomal-mitochondrial crosstalk are the two important mechanisms that lysosome regulates aging,and it is well known that iron plays a pivotal role in various cell metabolic activities[2,3].Accumulating evidence shows that there is a close relationship between lysosome and mitochondria,yet little is known about the exact role of them.The discovery that iron deficiency mediates lysosomal-mitochondrial crosstalk has presented a new therapeutic avenue for managing aging and aging-related diseases. | Lingzhi Wang Qun Zhou Linxi Chen Jinyong Jiang | 2020 | Acta Biochimica et Biophysica Sinica2020，52，11： | 1 |
| 15 | Highly sensitive piezoresistive and thermally responsive fibrous networks from the in situ growth of PEDOT on MWCNT-decorated electrospun PU fibers for pressure and temperature sensing显示文摘Flexible electronics have demonstrated various strategies to enhance the sensory ability for tactile perception and wearable physiological monitoring.Fibrous microstructures have attracted much interest because of their excellent mechanical properties and fabricability.Herein,a structurally robust fibrous mat was first fabricated by electrospinning,followed by a sequential process of functionalization utilizing ultrasonication treatment and in situ polymerization growth.Electrospun polyurethane(PU)microfibers were anchored with multi-walled carbon nanotubes(MWCNTs)to form conductive paths along each fiber by a scalable ultrasonic cavitation treatment in an MWCNT suspension.After,a layer of poly(3,4-ethylene dioxythiophene)(PEDOT)was grown on the surface of PU fibers decorated with MWCNTs to enhance the conductive conjunctions of MWCNTs.Due to the superior electromechanical behaviors and mechanical reinforcement of PEDOT,the PEDOT/MWCNT@PU mat-based device exhibits a wide working range(0–70 kPa),high sensitivity(1.6 kPa−1),and good mechanical robustness(over 18,000 cycles).The PEDOT/MWCNT@PU mat-based sensor also demonstrates a good linear response to different temperature variations because of the thermoelectricity of the PEDOT/MWCNT composite.This novel strategy for the fabrication of multifunctional fibrous mats provides a promising opportunity for future applications for high-performance wearable devices. | Yunyun Luo Libo Zhao Guoxi Luo Linxi Dong Yong Xia Min Li Ziping Li Kaifei Wang Ryutaro Maeda Zhuangde Jiang | 2023 | Microsystems & Nanoengineering2023，9，5： | 0 |
| 16 | TiO_(2)/In_(2)S_(3)S-scheme photocatalyst with enhanced H_(2)O_(2)-production activity显示文摘Photocatalytic production of hydrogen peroxide(H_(2)O_(2))is an ideal pathway for obtaining solar fuels.Herein,an S-scheme heterojunction is constructed in hybrid TiO_(2)/In_(2)S_(3)photocatalyst,which greatly promotes the separation of photogenerated carriers to foster efficient H_(2)O_(2)evolution.These composite photocatalysts show a high H_(2)O_(2)yield of 376μmol/(L·h).The mechanism of charge transfer and separation within the S-scheme heterojunction is well studied by computational methods and experiments.Density functional theory and in-situ irradiated X-ray photoelectron spectroscopy results reveal distinct features of the S-scheme heterojunction in the TiO_(2)/In_(2)S_(3)hybrids and demonstrate charge transfer mechanisms.The density functional theory calculation and electron paramagnetic resonance results suggest that O_(2)reduction to H_(2)O_(2)follows stepwise one-electron processes.In_(2)S_(3)shows a much stronger interaction with O_(2)than TiO_(2)as well as a higher reduction ability,serving as the active sites for H_(2)O_(2)generation.The work provides a novel design of S-scheme photocatalyst with high H_(2)O_(2)evolution efficiency and mechanistically demonstrates the improved separation of charge carriers. | Yi Yang Bei Cheng Jiaguo Yu Linxi Wang Wingkei Ho | 2023 | Nano Research2023，16，4： | 0 |
| 17 | Observations on potential novel transcripts from RNA-Seq data显示文摘With the rapid development of next generation deep sequencing technologies,sequencing cDNA reverse-transcribed from RNA molecules(RNA-Seq)has become a key approach in studying gene expression and transcriptomes.Because RNA-Seq does not rely on annotation of known genes,it provides the opportunity of discovering transcripts that have not been annotated in current databases.Studying the distribution of RNASeq signals and a systematic view on the potential new transcripts revealed from the signals is an important step toward the understanding of transcriptomes. | Chao YE Linxi LIU Xi WANG Xuegong ZHANG | 2011 | Frontiers of Electrical and Electronic Engineering in China2011，6，2： | 0 |
| 18 | 金属核及氧化铈的物理化学性质对一氧化碳氧化的影响显示文摘氧化铈独特的氧化还原性能使其适合用作氧化反应中的催化剂或载体.氧化铈负载的过渡金属纳米粒子或孤立的单原子提供了金属-载体界面,从而降低了去除界面氧原子的能耗,提供了可以参与ManVanKulvian氧化过程的活性氧物种.CO氧化是测试氧化铈负载催化剂还原性的主要探针反应,并且它常见于在相对低温下消除CO的各种应用中.在过量H2中优先氧化CO(PROX)反应可控制CO浓度达到超低水平,以防止氢氧化电催化剂中毒.催化剂在CO氧化反应中的活性和在PROX反应中对CO和H2的选择性取决于金属物种的种类和分散性、CeO2的结构和化学性质以及催化剂的合成方法.在这篇综述中,我们总结了最近发表的关于CeO2负载的金属纳米粒子和单原子催化CO氧化和PROX反应的相关工作;以及不同的负载金属和同种金属在普通CeO2表面上的反应性.我们还总结了密度泛函理论计算中提出的最可能的反应机理;并且讨论了各种负载型金属在PROX反应中影响CO氧化选择性的因素. | Linxi Wang Shyam Deo Kerry Dooley Michael J.Janik Robert M.Rioux | 2020 | Chinese Journal of Catalysis2020，41，6： | 0 |
| 19 | Electron transfer dynamics in Schottky junction photocatalyst during electron donor-assisted hydrogen production显示文摘Electron donors(EDs)are widely used to improve the H 2 production performance of Schottky junction photocatalysts,but the functions of EDs are still unknown from the perspective of electron transfer dy-namics.Herein,Pt nanocluster-decorated CdS nanorod is successfully prepared to construct a typical CdS/Pt Schottky junction.Pt nanoclusters with a diameter of∼2 nm are deposited on the surface of CdS nanorods by in situ photoreduction at sub-zero temperature.The CdS/Pt photocatalyst using lactic acid shows a higher H_(2)production rate of 4762μmol g^(-1)h^(-1)compared to that using methanol,tri-ethanolamine,and glycerol.To understand the cause,the dynamics of photogenerated carriers in CdS/Pt photocatalysts during ED-assisted H_(2)production are revealed by femtosecond transient absorption spec-troscopy.Among the four organic EDs,lactic acid enables the fastest electron transfer rate of 1.8×10^(9)s^(-1)and the highest electron transfer efficiency of 76%at the CdS/Pt interface due to the most efficient hole consumption.This work sheds light on the importance of efficient interfacial electron transfer for im-proving the photocatalytic performance of Schottky junction photocatalysts. | Jianjun Zhang Jingjing Liu Zheng Meng Sanjib Jana Linxi Wang Bicheng Zhu | 2023 | Journal of Materials Science & Technology2023，，28： | 0 |
| 20 | Molecular-level Engineering of S-scheme Heterojunction:the Site-specific Role for Directional Charge Transfer显示文摘The promising S-scheme heterojunction photocatalysts are considered as a novel frontier due to their superiority in various solar-driven energy-related applications.Recently,a novel atom-specific tailoring strategy has been introduced on the construction of S-scheme het-erojunction for promoting the electronic transferability.The S-scheme heterojunction is regulated by integrating high-crystalline carbon nitride with Co-doped CeO_(2).Specifically,this atom-specific regulation of S-scheme heterojunction boosts directional electron-driving effect towards functionalized Co sites,benefit-ing for effective photogenerated charge carrier transferability.Moreover,a series of tracking characterizations show that Co-embedded modification promotes CO_(2)photoreduction into hydrogenation steps,resulting in high performance towards CO_(2)-to-CH_(4)photoreduction,which provides new opportunities for the development of multifunctional cooperation in heterogeneous photocatalysis. | Jianjun Zhang Linxi Wang Mitra Mousavi Jahan B.Ghasemi Jiaguo Yu | 2022 | Chinese Journal of Structural Chemistry2022，41，6： | 0 |
