摘　　要：太阳能光电化学(PEC)水分解对可持续绿色能源开发有着重要意义。随着研究的推进,目前作为PEC系统核心组件的BiVO_(4)光阳极面临着尺寸放大和长时间稳定性的挑战。优越的全共形涂层策略不受底物尺寸限制,能够抑制BiVO_(4)半导体的光腐蚀,创造多功能界面,进一步与异质结、助催化剂等协同作用,有望实现大规模PEC水分解器件1000 h的稳定运行。本综述简要介绍了PEC水分解的基本原理以及具备代表性的器件的发展现状,阐述了面向大尺寸光阳极的全共形涂层的重要概念和主要设计原则,总结了近年来可实现全共形沉积涂层材料的最新进展,包括分子催化剂、金属氧化物/氢氧化物、碳化物/硫化物/磷化物和金属有机框架(MOFs),并讨论了更加具有发展潜力的全共形涂层的关键特性。最后对BiVO_(4)光阳极全共形涂层的未来发展趋势做出展望。Solar photoelectrochemical(PEC)water splitting holds significant importance for the development of sustainable green energy.With ongoing research,the BiVO_(4)photoanode,a core component of PEC systems,faces challenges in scaling up and maintaining long-term stability.The superiority of fully conformal coating strategies lies in their lack of substrate size constraints,ability to suppress photo-corrosion of the BiVO_(4)semiconductor,creation of multifunctional interfaces,and potential synergistic action with heterojunctions and promoter catalysts,which may facilitate the stable operation of large-scale PEC water splitting devices for over 1000 hours.This review briefly introduces the basic principles of PEC water splitting and the development status of representative devices,elaborates on the important concept and main design principles of fully conformal coatings aimed at large-scale photoanodes,summarizes recent advances in materials capable of achieving fully conformal deposition coatings,including molecular catalysts,metal oxides/hydroxides,carbonized/sulfurized/phosphorized materials,and metal-organic frameworks(MOFs),and discusses key characteristics of fully conformal coatings with greater development potential.Finally,it presents a prospective view on future trends in fully conformal coatings for BiVO_(4)photoanodes.
