摘要:

二氧化碳浓度持续升高导致的温室效应已在全球范围内引发极端天气、冰川融化等一系列生态环境问题。为降低二氧化碳含量,改善气候变暖带来的恶劣影响,研发高效、绿色、安全的二氧化碳处理技术,促进碳资源循环可持续发展刻不容缓。熔盐离子液体作为一种良好的电化学转化介质,为二氧化碳还原提供了一条极具应用前景的技术路线。综述了国内外近几年高温熔盐中二氧化碳的捕获与电化学还原的研究,简述了熔盐电沉积碳的电化学机理和热力学机制,对不同形貌高附加值碳材料:无定形碳、碳球和碳纳米管的制备进行了总结,最后对未来发展方向做出展望。

Abstract:

The greenhouse effect caused by the continuous increase of carbon dioxide concentration has caused a series of ecological and environmental problems such as extreme weather and melting of glaciers around the world. In order to reduce carbon dioxide content and improve the adverse impact of climate warming, it is urgent to develop efficient, green and safe processing technologies and promote the sustainable development of carbon resource cycle. Molten salt ionic liquid, as a good electrochemical conversion medium, provides a promising technical route for carbon dioxide reduction. The research on the capture and electrochemical reduction of carbon dioxide in high-temperature molten salt at home and abroad in recent years is reviewed, and the electrochemical and thermodynamic mechanisms of molten salt electrodeposited carbon are briefly described. The preparation of high value-added carbon materials with different morphologies: amorphous carbon, carbon spheres and carbon nanotubes are summarized, and finally the future development direction is prospected.

Key words: Molten salt electrochemistry, Carbon dioxide, Carbon material, High value utilization
