摘要
电催化二氧化碳还原能够有效地存储和利用可再生能源并缓解温室效应。发展高效的二氧化碳还原催化剂是抑制析氢提升二氧化碳还原活性的有效方法。铜是目前报道的非常有潜力的二氧化碳还原催化剂。但是,铜往往表现出比较低的二氧化碳还原至一氧化碳的活性。对Cu纳米线引入S和In制备Cu-In-S用于二氧化碳还原,结果表明,Cu-In-S表现出高效的二氧化碳还原活性,其催化电流密度和还原至一氧化碳的法拉第效率有了明显的提升。S的引入有效地提升了电催化剂的粗糙度,提升其电化学活性面积;In的引入有效地抑制了析氢,提高了二氧化碳还原至一氧化碳的活性。
Electrocatalytic carbon dioxide(CO2)reduction is an efficient strategy for renewable energy storage and utilization as well as relieving green house effect.The development of efficient catalysts for CO2 reduction is an effective route to suppress hydrogen evolution and improve CO2 reduction activity.Copper has been revealed as a promising candidate for CO2 reduction,however,it exhibits relatively low selectivity to carbon monoxide(CO).Cu-In-S was prepared by introducing S and In to Cu nanowires for CO2 reduction.It exhibits highly efficient performance for CO2 reduction,the current density and Faraday efficiency to carbon monoxide have been significantly improved.The introduction of S can effectively increase the roughness of the electrocatalyst and increase its electrochemical active area.The introduction of In effectively inhibits hydrogen evolution and improves the activity of CO2 reduction to carbon monoxide.
