摘要

利用可见光催化还原CO₂制备有机燃料可以同时缓解CO2的排放和解决能源危机，主要介绍了光催化还原CO2的影响因素，综述了近年来用于可见光响应光催化还原CO₂的半导体材料的研究进展，包括硫化物、氧化物及一些新型可见光响应的半导体材料与其改性材料，总结了不同种类催化剂的优势，提出鉴于可见光作用下转化CO₂为有用燃料转化效率极低，今后应选择并开发合适带隙的高活性半导体、鉴别半导体的活性位点、反应介质的筛选、优化操作条件等。

Abstract：

Photocatalytic reduction of CO₂ to prepare organic fuels under visible light can mitigate the emission of CO^₂and solve the energy crisis simultaneously. The influencing factors of photocatalytic reduction of CO₂ were mainly introduced. Recent progress of the semiconductor materials including sulfide, oxide and some novel visible light response and modified materials, used for photocatalytic reduction of CO₂ under visible light irradiation were reviewed. And the advantages of different kinds of catalysts and the direction of exploration in the future were summarized. It is pointed out that because the efficiency for photocatalytic conversion of CO₂ into useful fuel under visible is very low, chosing and developing suitable high active semiconductor, identifying the active site of semiconductor, selecting the reaction medium, and optimizing the operation conditions should be done in the future.

Key words： visible light photocatalyst reduction of CO₂
