摘要
由于不断增加的二氧化碳排放导致全球变暖,且能源短缺等问题日益恶化,将二氧化碳电化学还原为高附加值化学品和燃料引起了极大的兴趣,设计高效催化剂对实现二氧化碳的高效选择性转化具有重要意义.在所探索的各种催化剂中,铜基催化剂具有良好的开发潜力,可用于烃类生产.本文综述了铜基电化学二氧化碳转化材料的最新进展.分别从尺寸结构到不同形式(合金、氧化物)的铜基催化剂,以及分子催化剂等方面展开,重点讨论铜基催化剂上二氧化碳电解还原的反应机理.最后,对未来高效铜基催化剂的设计提出展望,以促进二氧化碳转化的可持续发展.
The electrochemical reduction of carbon dioxide(CO2)to useful chemicals and fuels has attracted enormous interest since the deteriorating global warming and energy shortage problems resulted from ever-increasing CO2 emission.Designing efficient catalysts is of capital significance to realize the efficient and selective conversion of CO2.Among various catalysts explored,copper-based compounds have promising potentials with acceptable efficiency for hydrocarbon production.Herein,recent advances on copper-based materials are summarized for electrochemical CO2 conversion.We intend to include the dimensional structure,different forms(alloy,oxide)and molecular catalysts in copper-based catalysts.Moreover,the reaction mechanisms of CO2 electroreduction on Cu-based catalysts are emphatically discussed.Finally,potential directions are also proposed for future design of highly efficient Cu-based catalysts to promote the rapid development of CO2 conversion for sustainable world.
