21 世纪以来，随着CO₂ 为主的温室气体排放量不断增加，寻求新型能源来构建低碳型社会的诉求越来越迫切。其中以太阳能驱动转化CO₂ 为碳氢燃料的技术，可将CO2 转化成甲烷、甲醇、甲酸或C₂₊ 等高附加值的碳氢燃料，是实现全球碳平衡的有效途径之一，具有巨大潜力。半导体材料是决定光催化还原CO₂ 过程进行的重要因素之一，因此探索和开发高效光催化功能材料是当今研究的主要方向。本文综述了近几年来作者课题组在光催化还原CO₂ 为碳氢燃料方面的重要研究进展，主要涉及TiO₂ 基系列光催化材料，V、W、Ge、Ga、C₃N₄ 基等系列光催化材料的结构组分调控。

With the increase of CO₂ greenhouse gas emissions, seeking new energy sources to build a low carbon society has become more urgent since the 21st century. The conversion of CO₂ to valuable hydrocarbon fuel driven by solar energy is of great potential and promising to realize the global carbon balance. Exploring semiconductor materials is very important for the photoreduction of CO₂. Therefore, it will be the main research direction to fabricate highly efficient photocatalysis materials. This paper reviews recent research on photocatalytic reduction of CO₂ to the hydrocarbon fuels in our groups, mainly focusing on nanostructure and component regulations of semiconductor catalysts, including TiO₂, V, W, Ge Ga based materials, C₃N₄ based and some other materials, for the photocatalytic reduction of CO₂.
