介绍了铟的不同沉积方法及铟电极在CO2电还原中的应用。在铟的沉积方法中,以硫酸盐型电镀铟的效果较好,并且较为实用。本文还综述了铟作为电极在水溶性介质与非水介质中电还原CO2的研究概况,分析了温度、压力、电极电位以及电解质等因素对其还原选择性及法拉第效率的影响。 The different deposition methods of indium and the application of indium electrode in CO2 reduction are introduced. In the indium deposition method, the sulfate type plating indium better, and more practical. This paper also reviewed the research status of indium as an electrode for the electro-reduction of CO2 in water-soluble and non-aqueous media. The effects of temperature, pressure, electrode potential and electrolyte on the reduction selectivity and Faraday’s efficiency were also reviewed.
