光催化二氧化碳还原研究进展

Development of Functional Materials for Photocatalytic Reduction of CO_(2)

21世纪以来,随着CO_(2)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CO_(2)为碳氢燃料的技术,可将CO_(2)转化成甲烷、甲醇、甲酸或C_(2+)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CO_(2)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CO_(2)为碳氢燃料方面的重要研究进展,主要涉及TiO_(2)基系列光催化材料,V、W、Ge、Ga、C_(3)N_(4)基等系列光催化材料的结构组分调控。

With the increase of CO_(2) greenhouse gas emissions,seeking new energy sources to build a low carbon society has become more urgent since the 21st century.The conversion of CO_(2) 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 CO_(2).Therefore,it will be the main research direction to fabricate highly efficient photocatalysis materials.This paper reviews recent research on photocatalytic reduction of CO_(2) to the hydrocarbon fuels in our groups,mainly focusing on nanostructure and component regulations of semiconductor catalysts,including TiO_(2),V,W,Ge Ga based materials,C_(3)N_(4) based and some other materials,for the photocatalytic reduction of CO_(2).
