Carbon Energy 2024年第4期6卷 12-21页

作者： Zhiting Liang Meng Li Kai‐Hang ye Tongxin Tang zhan.Lin yuying Zheng yongchao Huang Hongbing Ji Shanqing zhan. Guangzhou Key Laboratory of Clean Transportation Energy Chemistry School of Chemical Engineering and Light IndustryGuangdong University of TechnologyGuangzhouChina Chemical Engineering Guangdong Laboratory Jieyang Branch of ChemistryJieyangChina Key Laboratory for Water Quality and Conservation of the Pearl River delta Institute of Environmental Research at Greater Bay AreaMinistry of EducationGuangzhou UniversityGuangzhouChina State Key Laboratory Breeding Base of Green‐Chemical Synthesis Technology Institute of Green Petroleum Processing and Light Hydrocarbon ConversionCollege of Chemical EngineeringZhejiang University of TechnologyHangzhouChina School of Environment and Science Centre for Catalysis and Clean EnergyGriffith UniversityGold Coast CampusSouthportQueenslandAustralia

BiVO_(4)is one of the most promising photoanode materials for photoelectrochemical(PEC)solar energy conversion,but it still suffers from poor photocurrent density due to insufficient light‐harvesting efficiency(LHE),weak photogenerated charge separation efficiency(Φ_(Sep)),and low water oxidation efficiency(Φ_(OX)).Herein,we tackle these challenges of the BiVO_(4)photoanodes using systematic engineering,including catalysis engineering,bandgap engineering,and morphology *** particular,we deposit a niCoO_(x)layer onto the BiVO_(4)photoanode as the oxygen evolution catalyst to enhance theΦ_(OX)of Fe‐g‐C_(3)n_(4)/BiVO_(4)for PEC water oxidation,and incorporate Fe‐doped graphite‐phase C_(3)n_(4)(Fe‐g‐C_(3)n_(4))into the BiVO_(4)photoanode to optimize the bandgap and surface areas to subsequently expand the light absorption range of the photoanode from 530 to 690 nm,increase the LHE andΦ_(Sep),and further improve the oxygen evolution reaction activity of the niCoO_(x)catalytic ***,the maximum photocurrent density of the as‐prepared niCoO_(x)/Fe‐g‐C_(3)n_(4)/BiVO_(4)is remarkably boosted from 4.6 to 7.4 mA cm^(−2).This work suggests that the proposed systematic engineering strategy is exceptionally promising for improving LHE,Φ_(Sep),andΦ_(OX)of BiVO_(4)‐based photoanodes,which will substantially benefit the design,preparation,and large‐scale application of next‐generation high‐performance photoanodes.
