摘要
近年来,CO_(2)排放引起的温室效应造成了气候变暖和冰川融化等严重的生态环境问题。因此,寻求绿色、可持续和低成本的CO_(2)处理技术,促进碳资源高效转化已成为研究的热点课题。熔盐电化学处理工艺具有转化效率高、能耗低以及操作简便等优点,为将CO_(2)转化为高附加值的先进碳质材料提供了一条重要的技术路线。经过对熔盐电化学领域不断地深入研究,实现了碳纳米球、碳纳米管、石墨烯和碳纳米片等碳质材料的合成控制。文中主要对熔盐电化学还原CO_(2)制备不同形貌碳质材料,以及其转化机制进行了概述,为未来碳质材料的研究提供一定的参考。
In recent years,the greenhouse effect caused by CO_(2) emissions has caused severe ecological and environmental problems,such as climate warming and glacier melting.Therefore,seeking green,sustainable and low-cost CO_(2) treatment technology to promote the efficient transformation of carbon resources has become an important research topic.Molten salt electrochemistry methods with the advantages of high conversion efficiency,low energy consumption and simple operation,provide an important technical route for converting CO_(2) to high value-added carbon materials.After years of research in molten salt electrochemistry,researchers have synthesized carbon nanospheres,carbon nanotubes,graphene and carbon nano sheets.In this paper,the preparation methods for the electrochemical conversion of CO_(2) to carbonaceous materials with different morphologies by molten salt in recent years are summarized,and the conversion mechanism is briefly described as well.Finally,this paper prospects the development direction for carbon materials in the future.
