光催化还原CO2反应催化剂的研究进展

摘要

Greenhouse gas CO2 is one of the primary causes of global wanning. Using solar energy to make the reduction of CO2 into hydrocarbon organics will benefit the environmental protection and the efficient utilization of energy. The photocatalysts for the pholocatalytic reduction of carbon dioxide are introduced, including TiO2, metal complexes and some other metal oxides. The process of preparing these catalysts, the feature of structure, the reaction conditions of photocatalytic reduction of CO2 and the existed problems are described. Through the design of catalysts to improve the pho tocatalytic reactivity and the efficient utilization of light will be the focus of future research.%温室气体CO2是全球变暖的一个主要原因,利用太阳能将CO2还原为烃类等有机物将给环境保护和能源利用带来益处.介绍了CO2光催化还原反应中的催化剂,主要涉及TiO2、金属配合物以及一些其它金属氧化物.阐述了各类催化剂的制备过程、结构特征、光催化还原CO2反应条件以及催化剂存在的问题.通过催化剂设计,提高光催化反应活性和光利用效率是今后研究的重点.
