二氧化碳捕集材料的研究进展

Research progress of CO2 capture materials

摘要:

二氧化碳过度排放所导致的全球变暖已成为环境危机的一个首要问题，所以中国提出的实现碳达峰和碳中和的战略目标势在必行。为了解决这个问题，科研工作者们采用多种多样的二氧化碳捕集和储存技术。该文重点介绍了碳类材料、沸石、金属有机骨架材料、水滑石类材料、金属氧化物及其盐以及负载胺基材料等主要的CO2吸附材料的最新研究进展，详细介绍了各种吸附剂的吸附机理、性能的优缺点、改进的方向以及现在面临的挑战，并对吸附材料未来发展方向进行了展望。

Abstract:

Global warming caused by excessive CO2 emissions has become a primary issue in the environmental crisis, and hence it is imperative to achieve the strategic objectives of peak carbon dioxide emissions and carbon neutrality proposed by our nations. To solve this problem, a variety of CO2 capture and storage technologies have been adopted by numerous scientific researchers. This article focuses on major CO2 adsorbents, such as carbon-based materials, zeolites, metal organic framework materials, hydrotalcite materials, metal oxides and supporting amine-based materials, etc. Moreover, the latest research progress of CO2 adsorbents, including the adsorption mechanism, performance advantages and disadvantages, directions of improvement and current challenges, has been introduced in detail, and prospects for future development of the adsorption materials have been provided.
