| 1 | In-situ incorporation of Copper (Ⅱ) porphyrin functionalized zirconium MOF and TiO2 for efficient photocatalytic CO2 reduction显示文摘As one of the highly effective methods to prepare catalysts for photocatalytic reduction of CO2 into valueadded chemicals,using metalloporphyrin as light-harvesting mixed ligand to modify metal-organic framework(MOF)is very valuable since it can greatly improve the prophyrin dispersibility and consequently inhibit its potential agglomeration.Herein,we employed a one-pot synthetic strategy to chemically immobilize Cu(II)tetra(4-carboxylphenyl)porphyrin(CuTCPP)into UiO-66 MOF structure through coordination mode.Meanwhile,in-situ growth of TiO2 nanoparticles onto the MOF is actualized with the generation of CuTCPP c UiO-66/TiO2(CTU/TiO2)composites.Under Xe lamp irradiation(λ>300 nm),the catalytic result presents that an optimal value of 31.32 μmol g^-1 h^-1 CO evolution amount,about 7 times higher than that of pure TiO2 was obtained through the photocatalysis.It is supposed owning to a consistent augment of light absorption derived from chemically implanted porphyrin derivative,which is simultaneously functioning with an efficacious separation of photo-induced carries given by the newly engendered composites between MOF and TiO2,an effective catalytic activity and approving recyclability of CTU/TiO2 can be achieved in the photocatalytic reduction of CO2 into CO. | Lei Wang Pengxia Jin Shuhua Duan Houde She Jingwei Huang Qizhao Wang | 2019 | Science Bulletin2019，64，13： | 16 |
| 2 | Construction of ternary CuO/CuFe_(2)O_(4)/g-C_(3)N_(4)composite and its enhanced photocatalytic degradation of tetracycline hydrochloride with persulfate under simulated sunlight显示文摘In this study,a graphitic carbon nitride(g-C_(3)N_(4))based ternary catalyst Cu O/Cu Fe_(2)O_(4)/gC_(3)N_(4)(CCCN)is successfully prepared thorough calcination method.After confirming the structure and composition of CCCN,the as-synthesized composites are utilized to activate persulfate(PS)for the degradation of organic contaminant.While using tetracycline hydrochloride(TC)as pollutant surrogate,the effects of initial p H,PS and catalyst concentration on the degradation rate are systematically studied.Under the optimized reaction condition,CCCN/PS is able to give 99%degradation extent and 74%chemical oxygen demand removal in assistance of simulated solar light,both of which are apparently greater than that of either Cu O/Cu Fe_(2)O_(4)and pristine g-C_(3)N_(4).The great improvement in degradation can be assignable to the effective separation of photoinduced carriers thanks to the integration between Cu O/Cu Fe_(2)O_(4)and g-C_(3)N_(4),as well as the increased reaction sites given by the g-C_(3)N_(4)substrate.Moreover,the scavenging trials imply that the major oxidative matters involved in the decomposition are hydroxyl radicals(·OH),superoxide radicals(·O_(2)^(-))and photo-induced holes(h^(+)). | Lei Wang Xiaolei Ma Guofang Huang Rui Lian Jingwei Huang Houde She Qizhao Wang | 2022 | Journal of Environmental Sciences2022，34，2： | 5 |
| 3 | Construction of TiO_(2)-covalent organic framework Z-Scheme hybrid through coordination bond for photocatalytic CO_(2) conversion显示文摘In this work,a covalent organic framework(COF),which is constructed by the building blocks of[5,10,15,20-tetrakis(4-aminophenyl)porphinato]copper(Ⅱ)(CuTAPP)and p-benzaldehyde,is employed to integrate with TiO_(2) for the purpose of establishing a Z-scheme hybrid.Within the system,isonicotinic acid performs the role of a bridge that connects the two components through a coordination bond.Further photocatalytic application reveals the hybrid framework is able to catalyze CO_(2) conversion under simulated solar light,resulting in CO production rate of 50.5 μmol g^(-1)·h^(-1),about 9.9 and 24.5 times that of COF and pristine TiO_(2),respectively.The ameliorated catalytic performance owes much to the por-phyrin block acting as photosensitizer that augments the light absorbance,and the establishment of Z-scheme system between the inorganic and orga nic comp on ents that enhances the separati on of the carriers.In addition,the chemical bridge also ensures a steady usage and stable charge delivery in the catalysis.Our study sheds light on the development of versatile approaches to covalently in corporate COFs with inorga nic semic on ductors. | Lei Wang Guofang Huang Liang Zhang Rui Lian Jingwei Huang Houde She Chunli Liu Qizhao Wang | 2022 | Journal of Energy Chemistry2022，31，1： | 3 |
| 4 | Research Progress of Ferrite Materials for Photoelectrochemical Water Splitting显示文摘Photoelectrochemical(PEC)water splitting is an effective strategy to convert solar energy into clean and renewable hydrogen energy.In order to carry out effective PEC conversion,researchers have conducted a lot of exploration and developed a variety of semiconductors suitable for PEC water splitting.Among them,metal oxides stand out due to their higher stability.Compared with traditional oxide semiconductors,ferrite-based photoelectrodes have the advantages of low cost,small band gap,and good stability.Interestingly,due to the unique characteristics of ferrite,most of them have various tunable features,which will be more conducive to the development of efficient PEC electrode.However,this complex metal oxide is also troubled by severe charge recombination and low carrier transport efficiency,resulting in lower conversion efficiency compared to theoretical value.Based on this,this article reviews the structure,preparation methods,characteristics and modification strategies of various common ferrites.In addition,we analyzed the future research direction of ferrite for PEC water splitting,and looked forward to the development of more efficient catalysts. | Yani Wang Jingwei Huang Lei Wang Houde She Qizhao Wang | 2022 | Chinese Journal of Structural Chemistry2022，41，1： | 2 |
| 5 | In situ conversion builds MIL-101@NiFe-LDH heterojunction structures to enhance the oxygen evolution reaction显示文摘The construction of rich phase interfaces to increase active reaction area in hybrid materials is an excellent strategy to improve electrochemical performance.Under this guideline,MIL-101@OX-metal organic framework(MOF)is constructed by the'MOF on MOF'method,then converts to MIL-101@NiFe-layered double hydroxides(LDH)by in situ transformation in alkaline solution.MIL-101@NiFe-LDH shows excellent electrochemical water oxidation performance.It needs only an overpotential of 215 m V to drive10 m A/cm^(2)of oxygen evolution reaction(OER),which is less than that of NiFe-LDH,MIL-101.In addition,MIL-101@NiFe-LDH has the smallest Tafel slope(55.1 mV/dec)compared with Ni Fe-LDH(61.1 m V/dec),MIL-101(150.8 m V/dec).The excellent water oxidation activity is due to the high phase interfaces derived from high specific surface area of MOF.This work offers an alternative method for making MOF/LDH heterostructures with an optimized phase interfaces and provides new insights for OER. | Jingwei Huang Kai Li Lei Wang Houde She Qizhao Wang | 2022 | Chinese Chemical Letters2022，33，8： | 0 |
| 6 | Enhanced performance of NiF_(2)/BiVO_(4)photoanode for photoelectrochemical water splitting显示文摘The serious surface charge recombination and fatigued photogenerated carriers transfer of the BiVO_(4)photoanode restrict its photoelectrochemical(PEC)water splitting performance.In this work,nickel fluoride(NiF_(2))is applied to revamp pure BiVO_(4)photoanode by using a facile electrodeposition method.As a result,the asprepared NiF_(2)/BiVO_(4)photoanode increases the dramatic photocurrent density by approximately 180%compared with the pristine BiVO_(4)photoanode.Furthermore,the correlative photon-to-current conversion efficiency,the charge injection,and the separation efficiency,as well as the hydrogen generation of the composite photoanode have been memorably enhanced due to the synergy of NiF_(2)and BiVO_(4).This study may furnish a dependable guidance in fabricating the fluoride-based compound/semiconductor composite photoanode system. | Ziwei ZHAO Kaiyi CHEN Jingwei HUANG Lei WANG Houde SHE Qizhao WANG | 2021 | Frontiers in Energy2021，15，3： | 0 |
