摘要:: 由化石能源消耗所引发的能源危机与环境污染，已成为了人类社会可持续发展亟待解决的一个首要问题。可见光催化技术利用太阳光为能源，通过光解水制氢、CO2还原、污染物降解等过程为从根本上解决上述问题提供了一个有效途径，对可持续发展战略具有重要意义。金属卤化铅钙钛矿(lead metal halide perovskite, LMHP)型光催化剂因其多样的晶体结构、合适的禁带宽度及丰富的空位，表现出优异的光电性能，为实现光催化剂的性能调控提供了多种手段，成为了当前的一个研究热点。近年来，金属卤化铅钙钛矿的研究与应用发展非常迅速，特别是在太阳能驱动的应用中，取得了一系列成果。详细综述了金属卤化铅钙钛矿型光催化材料在可见光催化能源开发和环境污染治理领域的研究进展，为进一步开发环保高效的光催化剂新材料提供新的思路。

Abstract:: The energy and environmental issues caused by the consumption of fossil fuels have become a primary problem that needs to be solved urgently for the sustainable development of human society. Visible-light-driven photocatalysis utilizes sunlight as the power source and provides an effective way to fundamentally solve the above problems through the processes including photolytic water splitting, CO2 reduction, and pollutant degradation. This is of great significance for the sustainable development strategies. The lead metal halide perovskite (LMHP) photocatalyst exhibits excellent photoelectric performance due to its diverse crystal structure, suitable bandgap width and abundant vacancies, which provides multitudinous ways for adjusting the photocatalytic performance. In recent years, the research and application of LMHP materials have developed very rapidly, especially in solar-driven applications, and a series of achievements have been reached. This review summarizes in detail the recent research progresses of visible-light-induced photocatalysis based on LMHP materials and special emphasis is focused on hydrogen production, CO2 reduction and pollutant degradation. This review may introduce new ideas for the further development of environmentally friendly and efficient new photocatalyst materials.
