光催化还原CO_(2)的研究进展

Study on Progress of Photocatalytic Reduction of CO_(2)

利用光催化还原CO_(2)是缓解全球变暖和解决能源紧张问题最具研究价值的方法之一。本文主要以构建异质结和负载金属纳米颗粒两种方法为出发点,以提高光催化剂的光响应范围、光生载流子的传递速度和还原CO_(2)产物选择性为目的,对近年的研究成果进行总结。并以提高光生电子的利用率为目标进行了设想,旨在为提高光催化CO_(2)还原催化剂的设计研究中提供帮助。

Photocatalytic reduction of CO_(2)is one of the most valuable methods to alleviate global warming and solve the problem of energy shortage.The construction of heterojunction and the loading of metal nanoparticles was taken as the starting point,in order to improve the light response range of photocatalyst,photocarrier transfer speed and reduction of CO_(2)product selectivity,the recent research results were summarized.In order to improve the utilization rate of photogenerated electron,it was envisaged to provide help for improving the design and research of photocatalytic CO_(2)reduction catalyst.
