| 6 | Functional additives for solid polymer electrolytes in flexible and high-energy-density solid-state lithium-ion batteries显示文摘Solid polymer electrolytes(SPEs)have become increasingly attractive in solid-state lithium-ion batteries(SSLIBs)in recent years because of their inherent properties of flexibility,processability,and interfacial compatibility.However,the commercialization of SPEs remains challenging for flexible and high-energy-density LIBs.The incorporation of functional additives into SPEs could significantly improve the electrochemical and mechanical properties of SPEs and has created some historical milestones in boosting the development of SPEs.In this study,we review the roles of additives in SPEs,highlighting the working mechanisms and functionalities of the additives.The additives could afford significant advantages in boosting ionic conductivity,increasing ion transference number,improving high-voltage stability,enhancing mechanical strength,inhibiting lithium dendrite,and reducing flammability.Moreover,the application of functional additives in high-voltage cathodes,lithium-sulfur batteries,and flexible lithiumion batteries is summarized.Finally,future research perspectives are proposed to overcome the unresolved technical hurdles and critical issues in additives of SPEs,such as facile fabrication process,interfacial compatibility,investigation of the working mechanism,and special functionalities. | Hao Chen Mengting Zheng Shangshu Qian Han Yeu Ling Zhenzhen Wu Xianhu Liu Cheng Yan Shanqing Zhang | 2021 | Carbon Energy2021，3，6： | 3 |
| 7 | Metal ion-promoted fabrication of melanin-like poly(L-DOPA)nanoparticles for photothermal actuation显示文摘Melanin-inspired polymers are currently the focus of growing interest for a wide range of applications ranging from energy to biomedical area.Whilst researchers have made numerous attempts to prepare and utilize polydopamine nanoparticles(PDA NPs),they have made limited progress in developing and discovering another typical functional mimic of natural melanin,poly(levodopa)(P(L-DOPA))NPs,probably due to the lack of facile synthetic strategies towards satisfactory structural and functional control of melanin-like NPs.Herein,we reported a one-pot preparation method towards P(L-DOPA)NPs with good yields and controllable size/property in an aqueous solution assisted by various metal ions(i.e.,Ni(II),Mg(II),Ca(II),Fe(III),Mn(II),Co(II),Zn(II)and Cd(II)).Interestingly,the resulting P(L-DOPA)NPs exhibited enhanced light absorption and photothermal behaviors compared with well-established PDA NPs,which can be employed to further fabricate kinds of photothermal composite actuators with promising performances such as folding,switching,and forward-moving.This study offers a facile and robust way to synthesize new synthetic melanins beyond PDA,and facilitates further functional discovery and evolution of melanin-inspired polymers and composites. | Xianheng Wang Lei Yang Peng Yang Wancai Guo Quan-Ping Zhang Xianhu Liu Yiwen Li | 2020 | Science China Chemistry2020，63，9： | 3 |
| 8 | Insights into the efficient charge separation over Nb_(2)O_(5)/2D-C_(3)N_(4) heterostructure for exceptional visible-light driven H_(2) evolution显示文摘Two-dimensional carbon nitride(2 D-C_(3) N_(4))nanosheets are promising materials in photocatalytic water splitting,but still suffer from easy agglomeration and fast photogene rated electron-hole pairs recombination.To tackle this issue,herein,a hierarchical Nb_(2) O_(5)/2 D-C_(3) N_(4) heterostructure is precisely constructed and the built-in electric field between Nb_(2)O_(5) and 2 D-C_(3) N_(4) can provide the driving force to separate/transfer the charge carriers efficiently.Moreover,the strongly Lewis acidic Nb_(2)O_(5) can adsorb TEOA molecules on its surface at locally high concentrations to facilitate the oxidation reaction kinetics under irradiation,resulting in efficient photogene rated electrons-holes separation and exceptional photocatalytic hydrogen evolution.As expected,the champion Nb_(2)O_(5)/2 D-C_(3)N_(4) heterostructure achieves an exceptional H2 evolution rate of 31.6 mmol g^(-1) h^(-1),which is 213.6 times and 4.3 times higher than that of pristine Nb_(2)O_(5) and2 D-C_(3)N_(4),respectively.Moreover,the champion heterostructure possesses a high apparent quantum efficiency(AQE)of 45.08%atλ=405 nm and superior cycling stability.Furthermore,a possible photocatalytic mechanism of the energy band alignment at the hetero-interface is proposed based on the systematical characterizations accompanied by density functional theory(DFT)calculations.This work paves the way for the precise construction of a high-quality heterostructured photocatalyst with efficient charge separation to boost hydrogen production. | Jia Yan Ting Wang Siyao Qiu Zhilong Song Wangqin Zhu Xianhu Liu Jiabiao Lian Chenghua Sun Huaming Li | 2022 | Journal of Energy Chemistry2022，31，2： | 3 |
| 9 | Biomass-derived nonprecious metal catalysts for oxygen reduction reaction: The demand-oriented engineering of active sites and structures显示文摘Oxygen reduction reaction(ORR)is an important electrochemical process for renewable energy conversion and storage applications such as fuel cells and metal-air batteries.ORR is sluggish in kinetics and requires a large amount of platinum group metal(PGM)-based catalysts to facilitate its slow reaction rate.Application of precious metals raises the cost and decreases the competitivity of these devices in the market.To address this challenge,PGM-free ORR catalysts have been intensively investigated as an alternative to replace the PGM-based catalysts and to promote the deployment of ORR-related applications.In particular,the biomass holds promising potential to be used as the precursor material for PGM-free ORR catalysts.This pathway has gained more and more attention in recent years.In this review,recent advances regarding biomass-derived ORR catalysts are summarized with a focus on the rational design of both active sites and porous structures which are the two key factors in determining ORR performance of catalysts.At the end,the perspectives of development of biomass-derived catalysts is discussed. | Lei Du Gaixia Zhang Xianhu Liu Amir Hassanpour Marc Dubois Ana CTavares Shuhui Sun | 2020 | Carbon Energy2020，2，4： | 3 |
| 10 | Interface Engineering of CoS/CoO@N‑Doped Graphene Nanocomposite for High‑Performance Rechargeable Zn–Air Batteries显示文摘Low cost and green fabrication of high-performance electrocatalysts with earth-abundant resources for oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)are crucial for the large-scale application of rechargeable Zn-air batteries(ZABs).In this work,our density functional theory calculations on the electrocatalyst suggest that the rational construction of interfacial structure can induce local charge redistribution,improve the electronic conductivity and enhance the catalyst stability.In order to realize such a structure,we spatially immobilize heterogeneous CoS/CoO nanocrystals onto N-doped graphene to synthesize a bifunctional electrocatalyst(CoS/CoO@NGNs).The optimization of the composition,interfacial structure and conductivity of the electrocatalyst is conducted to achieve bifunctional catalytic activity and deliver outstanding efficiency and stability for both ORR and OER.The aqueous ZAB with the as-prepared CoS/CoO@NGNs cathode displays a high maximum power density of 137.8 mW cm^−2,a specific capacity of 723.9 mAh g^−1 and excellent cycling stability(continuous operating for 100 h)with a high round-trip efficiency.In addition,the assembled quasi-solid-state ZAB also exhibits outstanding mechanical flexibility besides high battery performances,showing great potential for applications in flexible and wearable electronic devices. | Yuhui Tian Li Xu Meng Li Ding Yuan Xianhu Liu Junchao Qian Yuhai Dou Jingxia Qiu Shanqing Zhang | 2021 | Nano-Micro Letters2021，13，1： | 2 |
| 11 | Ultrasmall Nanoparticle ROS Scavengers Based on Polyhedral Oligomeric Silsesquioxanes显示文摘Although tremendous efforts have been devoted to the structural and functional tailoring of natural polyphenol-functionalized nan oparticles,preparing ultrasmall sized(<6 nm)particles with precisely-defined structures has remained a grand challenge.In this work,we reported the preparation of ultra-small and precisely structured polyhedral oligomeric silsesquioxanes(POSS)-based polyphenol nanopartides(T8^-,T10^-,and T12^-GAPOSS)by accurately functionalizing the POSS surface with plant polyphenol gallic acid units via thiol-Michael'click'reactions.Those polyphenol nanoparticles exhibited strong free radical scavenging capacity,good biocompatibility and ability to resist cell oxidative damage,which dem on strated great potentials in inhibiting oxidative stress in duced pathologies. | Zhan Li Haotian Li Jianhua Zhang Xianhu Liu Zhipeng Gu Yiwen Li | 2020 | Chinese Journal of Polymer Science2020，38，11： | 2 |
| 12 | The fabrication of homogeneous perovskite films on non-wetting interfaces enabled by physical modification显示文摘Conjugated polymers are commonly used as effective hole transport materials(HTMs) for preparation of high-performance perovskite solar cells. However, the hydrophobic nature of these materials renders it difficult to deposit photovoltaic perovskite layers on top via solution processing. In this article, we report a generic surface modification strategy that enables the deposition of uniform and dense perovskite films on top of non-wetting interfaces. In contrast to the previous proposed chemical modifications which might alter the optoelectronic properties of the interfacial layers, we realized a nondestructive surface modification enabled by introducing a layer of insulating mesoporous aluminum oxide(Al2O3). The surface energies of the typical non-wetting hole-transport layers(PTAA, P3 HT, and Poly-TPD) were significantly reduced by the Al2O3 modification. Benefiting from the intact optoelectronic properties of the HTMs, perovskite solar cells deposited on these interface materials show full open-circuit voltages( V OC) with high fill factors(FF) up to 80%. Our method provides an effective avenue for exploiting the full potential of the existing as well as newly developed non-wetting interface materials for the fabrication of high-performance inverted perovskite solar cells. | Jiang You Fei Guo Shudi Qiu Wenxin He Chuan Wang Xianhu Liu Weijian Xu Yaohua Mai | 2019 | Journal of Energy Chemistry2019，28，11： | 2 |
| 13 | Cation-vacancy induced Li+ intercalation pseudocapacitance at atomically thin heterointerface for high capacity and high power lithium-ion batteries显示文摘It is challenging to create cation vacancies in electrode materials for enhancing the performance of rechargeable lithium ion batteries (LIBs). Herein, we utilized a strong alkaline etching method to successfully create Co vacancies at the interface of atomically thin Co_(3−x)O_(4)/graphene@CNT heterostructure for high-energy/power lithium storage. The creation of Co-vacancies in the sample was confirmed by high-resolution scanning transmission electron microscope (HRSTEM), X-ray photoelectron spectroscopy (XPS) and electron energy loss near-edge structures (ELNES). The obtained Co_(3−x)O_(4)/graphene@CNT delivers an ultra-high capacity of 1688.2 mAh g^(−1) at 0.2 C, excellent rate capability of 83.7% capacity retention at 1 C, and an ultralong life up to 1500 cycles with a reversible capacity of 1066.3 mAh g^(−1). Reaction kinetic study suggests a significant contribution from pseudocapacitive storage induced by the Co-vacancies at the Co_(3−x)O_(4)/graphene@CNT interface. Density functional theory confirms that the Co-vacancies could dramatically enhance the Li adsorption and provide an additional pathway with a lower energy barrier for Li diffusion, which results in an intercalation pseudocapacitive behavior and high-capacity/rate energy storage. | Ding Yuan David Adekoya Yuhai Dou Yuhui Tian Hao Chen Zhenzhen Wu Jiadong Qin Linping Yu Jian Zhang Xianhu Liu Shi Xue Dou Shanqing Zhang | 2021 | Journal of Energy Chemistry2021，30，11： | 2 |

| 16 | Understanding the role of interface in advanced semiconductor nanostructure and its interplay with wave function overlap显示文摘As the proportion of interfaces increases rapidly in nanomaterials,properties and quality of interfaces hugely impact the performance of advanced semiconductors.Here,the effect of interfaces is explored by comparatively studying two InAs/AlSb superlattices with and without the thin InAsSb layers inserted inside each InAs layers.Through strain mapping,it indicates that the addition of interfaces leads to an increase of local strain both near interfaces and inside layers.Meantime,owing to the creation of hole potential wells within the original electron wells,the charge distribution undergoes an extra electron-hole alternating arrangement in the structure with inserted layers than the uninserted counterpart.Such a feature is verified to enhance electron-hole wave function overlap by theoretical simulations,which is a must for better optical performance.Furthermore,with an elaborate design of the inserted layers,the wave function overlap could be boosted without sacrificing other key device performances. | Chenyuan Cai Yunhao Zhao Faran Chang Xuebing Zhao Liting Yang Chongyun Liang Guowei Wang Zhichuan Niu Yi Shi Xianhu Liu Yuesheng Li Renchao Che | 2020 | Nano Research2020，13，6： | 1 |
| 17 | Flexible Ag Microparticle/MXene-Based Film for Energy Harvesting显示文摘Ultra-thin flexible films have attracted wide attention because of their excellent ductility and potential versatility.In particular,the energy-harvesting films(EHFs)have become a research hotspot because of the indispensability of power source in various devices.However,the design and fabrication of such films that can capture or transform di erent types of energy from environments for multiple usages remains a challenge.Herein,the multifunctional flexible EHFs with e ective electro-/photo-thermal abilities are proposed by successive spraying Ag microparticles and MXene suspension between on waterborne polyurethane films,supplemented by a hot-pressing.The optimal coherent film exhibits a high electrical conductivity(1.17×10^(4)S m^(-1)),excellent Joule heating performance(121.3℃)at 2 V,and outstanding photo-thermal performance(66.2℃ within 70 s under 100 mW cm^(-1)).In addition,the EHFs-based single-electrode triboelectric nanogenerators(TENG)give short-circuit transferred charge of 38.9 nC,open circuit voltage of 114.7 V,and short circuit current of 0.82μA.More interestingly,the output voltage of TENG can be further increased via constructing the double triboelectrification layers.The comprehensive ability for harvesting various energies of the EHFs promises their potential to satisfy the corresponding requirements. | Yunpeng Jia Yamin Pan Chunfeng Wang Chuntai Liu Changyu Shen Caofeng Pan Zhanhu Guo Xianhu Liu | 2021 | Nano-Micro Letters2021，13，12： | 1 |
| 18 | Mechanoluminescent hybrids from a natural resource for energy-related applications显示文摘Mechanoluminescent(ML)materials that directly convert mechanical energy into photon emission have emerged as promising candidates for various applications.Despite the recent advances in the development of both novel and conventional ML materials,the limited access to ML materials that simultaneously have the attributes of high brightness,low cost,self-recovery,and stability,and the lack of appropriate designs for constructing ML devices represent significant challenges that remain to be addressed to boost the practical application of ML materials.Herein,ML hybrids derived from a natural source,waste eggshell,with the aforementioned attributes are demonstrated.The introduction of the eggshell not only enables the preparation of the hybrid in a simple and cost-effective manner but also contributes to the homochromatism(red,green,or blue emission),high brightness,and robustness of the resultant ML hybrids.The significant properties of the ML hybrids,together with the proposed structural design,such as porosity or core–shell structure,could expedite a series of mechanic-optical applications,including the self-luminous shoes for the conversion of human motions into light and light generators that efficiently harvest water wave energy.The fascinating properties,versatile designs,and the efficient protocol of“turning waste into treasure”of the ML hybrids represent significant advances in ML materials,promising a leap to the practical applications of this flouring material family. | Chunfeng Wang Ronghua Ma Dengfeng Peng Xianhu Liu Jing Li Boru Jin Aixian Shan Yu Fu Lin Dong Wenchao Gao Zhong Lin Wang Caofeng Pan | 2021 | InfoMat2021，3，11： | 1 |

| 20 | Transactivating-transduction protein-polyethylene glycol modified liposomes traverse the blood-spinal cord and blood-brain barriers显示文摘Naive liposomes can cross the blood-brain barrier and blood-spinal cord barrier in small amounts. Liposomes modified by a transactivating-transduction protein can deliver antibiotics for the treatment of acute bacterial infection-induced brain inflammation. Liposomes conjugated with polyethylene glycol have the capability of long-term circulation. In this study we prepared transactivating-transduction protein-polyethylene glycol-modified liposomes labeled with fluorescein isothiocyanate. Thus, liposomes were characterized by transmembrane, long-term circulation and fluorescence tracing. Uptake, cytotoxicity, and the ability of traversing blood-spinal cord and blood-brain barriers were observed following coculture with human breast adenocarcinoma cells (MCF-7). Results demonstrated that the liposomes had good biocompatibility, and low cytotoxicity when cocultured with human breast adenocarcinoma cells. Liposomes could traverse cell membranes and entered the central nervous system and neurocytes through the blood-spinal cord and blood-brain barriers of rats via the systemic circulation. These results verified that fluorescein isothiocyanate-modified transactivating-transduction protein-polyethylene glycol liposomes have the ability to traverse the blood-spinal cord and blood-brain barriers. | Xianhu Zhou Chunyuan Wang Shiqing Feng Jin Chang Xiaohong Kong Yang Liu Shijie Gao | 2012 | Neural Regeneration Research2012，7，35： | 1 |
