CO2催化还原研究进展

Research progress on catalytic reduction of CO2

利用太阳能或电能将温室气体CO2转化成碳氢燃料,不仅是降低CO2浓度和温室效应影响的重要途径,也是缓解能源短缺问题的有效手段。CO2还原催化剂研制及相关技术已成为近年来催化领域的研究热点。本文按照光催化、电催化及光电催化的思路,对相应的还原机理及催化剂体系开展的相关重要研究进行了梳理和归纳,并对还原过程中存在的关键问题进行了总结和展望。

Converting greenhouse gas CO2 into hydrocarbon fuel with solar energy or electric energy is not only an important way to reduce concentration of CO2 and mitigate greenhouse-effect impact,but also an effective measure to alleviate energy shortage.The research on CO2 reduction catalyst and related routes has become a hot spot in the catalytic filed in recent years.In this paper,in terms of photocatalytic reduction,electrocatalytic reduction,and photoelectrocatalytic reduction,some important research on reduction principles and catalyst systems are reviewed,and key problems in reduction process are summarized.
