摘要
CO2作为温室气体,其捕集和存储有着重要的现实意义。多孔碳材料掺杂N原子后可以极大地改变材料的表面化学性质,增强表面碱性,在CO2吸附领域具有广泛的应用。基于N掺杂最新研究进展,本文系统地介绍了原位、后处理等掺N方法和不同孔道结构对CO2吸附分离或扩散传质的影响,总结归纳了材料的物理结构参数、表面化学性质与CO2吸附分离性能的关系,指出了各种制备方法存在的问题及解决的方法,为高性能的CO2吸附剂的定向设计、制备以及工业化提供了理论参考。
CO2 is regarded as a greenhouse gas. Its capture and storage has important practical significance. Porous carbon materials doped with N atoms can greatly change the surface chemical properties, strengthen basic surface, which have wide application in the field of CO2 adsorption. In this paper, based on the latest research progresses of N-doped carbon materials, the direct synthesis, post treatment strategies, etc. and pore structure of N-doped porous carbon for adsorption, separation or diffusion of CO2 were introduced in detail. The relationships between the physical structure parameters, surface chemistry of N-doped carbon materials and CO2 adsorption separation performance were systematically summarized. It was also pointed out the existing problems and the solutions of various treatment methods. Preparation and industrialization of high performance CO2 adsorbents provide theoretical support for the directional design.
