摘　　要：由于TiO_(2)光催化材料具有反应速度快、稳定性好、不产生二次污染等优点,常被应用于污染物降解、CO_(2)还原、制氢等领域,然而TiO_(2)可见光利用率低,限制了其进一步广泛应用。近年来,无铅卤系钙钛矿纳米晶由于其带隙可调、可见光吸收能力强等优势在光催化领域显示出巨大的潜力。相关研究表明:无铅卤系钙钛矿纳米晶可成功应用于CO_(2)还原、有机污染物降解等领域,效果显著。基于此,本文首先阐述了无铅卤系钙钛矿纳米晶的制备方法,并系统地总结了其在CO_(2)还原、制氢、污染物降解、NO去除等领域的应用研究进展,最后就现阶段无铅卤系钙钛矿纳米晶光催化材料研究中存在的问题及今后的研究方向进行了分析和展望。TiO_(2) based photocatalytic technology is of wide application in the fields of pollutant degradation,CO_(2) reduction,hydrogen production,etc.owing to its set of intriguing properties,including fast reaction speed,high visible light utilization efficiency,and no secondary pollution.However,the low utilization rate of visible light for TiO_(2) materials limits it further use.In recent years,lead-free halide perovskite nanocrystals are of great interest in the field of photocatalysis due to their notable advantages such as tunable band gap and high visible light absorption.Relevant studies show that lead-free halide perovskite nanocrystals can be successfully applied in the fields of CO_(2) reduction and organic pollutant degradation,with significant effects.This review describes the preparation methods of lead-free halide perovskite nanocrystals,and summarizes its applications in the fields of CO_(2) reduction,hydrogen production,pollutant degradation and NO removal systematically.Finally,the current issues of lead-free halide perovskite nanocrystals as photocatalytic materials and the outlook for the future directions are discussed and prospected.
