Study on Inhibition of Hydrogen Evolution Reaction During Photocatalytic Reduction of CO_(2) by Catalyst Adsorption and Activation

光催化还原CO_(2)作为缓解温室效应和能源问题的重要手段受到人们的重视,但光催化还原CO_(2)的效率依旧较低。原因之一是光催化还原CO_(2)与H_(2)O还原析氢之间的竞争反应。抑制光催化还原CO_(2)过程中的析氢反应,受到研究者的关注。本文基于光催化还原CO_(2)与H_(2)O还原之间存在的竞争反应,从催化剂比表面积、金属离子杂化、晶面选择、疏水界面构建及金属助催化剂等方面对增大CO_(2)吸附、活化和抑制析氢反应进行综述,旨在提高CO_(2)还原选择性催化剂的设计提供帮助。

Photocatalytic reduction of CO_(2) as an important solution to alleviate the greenhouse effect and energy problems has attracted much attention,but the efficiency of photocatalytic reduction of CO_(2) is still low.One of the reasons is the competitive reaction between photocatalytic reduction of CO_(2) and H_(2)O reduction of hydrogen evolution.Inhibition of hydrogen evolution in photocatalytic CO_(2) reduction has attracted the attention of researchers.Based on photocatalytic reduction reaction between CO_(2) and H_(2)O reduction of competition,from the specific surface area of catalyst,hybridization of metal ions,crystal,hydrophobic interface build and metal cocatalyst of increasing CO_(2) adsorption,activation and inhibition of hydrogen evolution reaction were reviewed.The design of selective catalysts for CO_(2) reduction was improved.
