二氧化碳电化学还原的研究进展

利用低品阶的可再生电能,将二氧化碳(CO_2)电化学还原生成高附加值的化学品或燃料,既可以"变废为宝"、减少CO_2排放,又能将可再生能源转变为高能量密度的燃料储存,具有重要的现实意义。电化学还原CO_2的研究,是目前世界范围内的研究热点,许多标志性的重要研究成果不断涌现。本文首先简要介绍了CO_2电化学还原的基本原理,然后概述了近5年来在其电催化剂材料和反应机理相关的实验与理论研究方面的昀新研究进展,昀后对其发展趋势进行了展望。

Recent Progress on Electrochemical Reduction of Carbon Dioxide

Conversion of carbon dioxide (CO₂) to value-added chemicals and fuels driven by low-grade renewable electricity is of significant interest since it serves the dual purpose of reducing atmospheric content of CO₂ by utilizing it as a feedstock and storing it in the form of high-energy-density fuels. In this regard, there are an increasing number of interesting developments taking place in the popular research focus area of electrochemical reduction of CO₂. This review first introduces the general principles of CO₂ electroreduction. Next, the latest progress relating to electrocatalytic materials and experimental and theoretical studies of the reaction mechanism has been discussed. Finally, the challenges and prospects for further development of CO₂ electroreduction have been presented.
