近年来，大气中二氧化碳含量的增加不仅导致了全球变暖，而且也引发了人们对光催化还原二氧化碳的极大兴趣。利用阳光以H2O还原CO2是解决当前日益严峻的环境挑战的创新方法。本文综述了光催化还原CO2的基本原理，讨论了光催化还原CO2效率的衡量标准，并总结了利用不同类型的半导体光催化剂，如TiO 2及其改性物、层状钙钛矿结构的Ag/Ala 4 Ti4 O 15（A = Ca，Ba，Sr）、铁电体LiNbO 3和等离子体光催化剂进行光催化还原CO2的研究进展。可见光捕获、新型等离子体光催化剂为该还原过程中的一些主要缺点提供了潜在的解决方案。有效的等离子体光催化剂，已显示出减少活动对二氧化碳与水在这里强调。虽然这一技术仍处于萌芽阶段，但建议进一步研究标准理论和综合格式，以开发具有高生产率和选择性的光催化剂。根据收集的结果，在这里还审查了巨大的前景和存在的机会，在此技术。
In recent years, the increasing level of CO2 in the atmosphere has not only contributed to global warming but has also triggered considerable interest in photocatalytic reduction of CO2. The reduction of CO2 with H2O using sunlight is an innovative way to solve the current growing environmental challenges. This paper reviews the basic principles of photocatalysis and photocatalytic CO2 reduction, discusses the measures of the photocatalytic efficiency and summarizes current advances in the exploration of this technology using different types of semiconductor photocatalysts, such as TiO2 and modified TiO2, layered-perovskite Ag/ALa4Ti4O15 (A = Ca, Ba, Sr), ferroelectric LiNbO3, and plasmonic photocatalysts. Visible light harvesting, novel plasmonic photocatalysts offer potential solutions for some of the main drawbacks in this reduction process. Effective plasmonic photocatalysts that have shown reduction activities towards CO2 with H2O are highlighted here. Although this technology is still at an embryonic stage, further studies with standard theoretical and comprehensive format are suggested to develop photocatalysts with high production rates and selectivity. Based on the collected results, the immense prospects and opportunities that exist in this technique are also reviewed here.
