光催化二氧化碳还原研究进展

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。

Development of Functional Materials for Photocatalytic Reduction of CO2

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.
