摘　　要：光催化产氢为解决日益严重的环境污染和不断加剧的能源危机等问题提供了新思路。钙钛矿因其优越的光电特性已成为太阳能制氢催化材料的研究热点。概述了钙钛矿的结构特性,阐述了钙钛矿光催化制氢原理,总结了3种钙钛矿制氢系统即光催化剂颗粒悬浮系统、光电化学系统、光伏驱动电化学系统的制氢原理及研究进展。未来,迫切需要探索新的半导体基光催化剂、改善光生电荷分离的新策略以及气体分离的新材料和新技术。同时,先进的表征技术尤其是原位和超快光谱分析方法,对于解释水分解反应的机理至关重要。Photocatalytic hydrogen production provides a new solution to the problems of increasingly serious environmental pollution and energy crisis.Perovskite has become a highlighted catalytic material for solar hydrogen production because of its superior photoelectric properties.In this paper the structural characteristics of perovskite were summarized,the principle of photocatalytic hydrogen evolution was expounded,the principle and research progress of hydrogen production of three kinds of perovskite-based hydrogen production systems,namely photocatalyst particle suspension system,photoelectrochemistry system,and photovoltaic-driven electrochemistry system were presented.In the future,it is urgent to develop novel semiconductor-based photocatalysts and approaches to improvement of photo-induced charge separation efficiency and up-to-date materials with technologies for gas separation.At the same time,some advanced characterization techniques,especially in-situ and ultra-fast spectroscopy,are crucial to interpretation of the mechanism of water splitting reaction.
