摘　　要：高温熔盐体系提供快速反应所需的条件和宽敞的电化学窗口,不仅可以活化吸收剂从而提高CO_2吸收容量和吸收速率,而且可以将CO_2电化学转化为高附加价值的碳材料或CO.本文对CO_2在高温熔盐中的吸收与电化学转化的研究进行综述,综合分析了高温熔盐吸收CO_2的影响因素以及CO_2在高温熔盐中的电化学转化过程、机理,并阐述了高温熔盐、气氛、电解条件和电极材料等因素对产物的类型、产物形貌以及电解能耗方面的影响.As reaction media, high-temperature molten salt provides a rapid-reaction condition and wide electro- chemical window, which can not only activate the absorbents to improve CO2 absorption capacity and absorption rate, but also play an important role in converting CO2 into value-added carbonaceous materials or CO. In this paper, we re- viewed the research advance in CO2 absorption and followed transformation in high temperature molten salts, and in- troduced the influencing factors for CO2 absorption and electrochemical mechanism and influencing factors for the elec- trochemical transformation of CO2 in the molten salts, as well as the impact on product type, product morphology and energy consumption by the factors concerning molten salt components, gas atmosphere, eletrolysis conditions and electrode materials respectively.
