摘要:

为应对全球气候危机,二氧化碳(CO2)捕集技术受到广泛关注。吸附法作为一项有前景的低成本CO2捕集技术,其研究核心在于吸附剂材料的开发。碳气凝胶材料具有比表面积高、孔隙结构丰富、孔径结构可调、再生能耗低等优点,同时拥有大量的表面活性位点,能够高效吸附CO2。利用可再生的生物质资源作为原料制备高性能碳气凝胶CO2吸附剂,是一种有效降低经济与环境成本的材料开发新途径。本文旨在整理和总结近年来国内外关于生物质碳气凝胶CO2吸附剂的研究进展,包括碳气凝胶吸附CO2的机理、制备方法以及性能表征,并着重关注其功能化方法。综合分析结果显示,生物质碳气凝胶凭借其高比表面积、良好的化学稳定性以及可调控的孔结构,展现出在CO2吸附领域的巨大潜力和广阔应用前景。未来应进一步探索生物质碳气凝胶的规模化制备技术及其在复杂工业环境中的实际应用,推动其从实验室研究向实际应用转化。

Abstract:

In response to the global climate crisis, carbon dioxide (CO2) capture technology has garnered widespread attention. As a promising low-cost CO2 capture technology, the core of adsorption research lies in the development of adsorbent materials. Carbon aerogel materials possess advantages such as high specific surface area, rich pore structure, adjustable pore size and low regeneration energy consumption along with a large number of surface active sites capable of efficiently adsorbing CO2. Utilizing renewable biomass resources as raw materials to prepare high-performance carbon aerogel CO2 adsorbents is a new approach to material development that effectively reduces economic and environmental costs. This review aimed to organize and summarize the recent research progress on biomass carbon aerogel CO2 adsorbents both domestically and internationally, including the mechanism of CO2 adsorption by carbon aerogels, preparation methods and performance characterization with a focus on their functionalization methods. Comprehensive analysis results indicated that biomass carbon aerogels with their high specific surface area, good chemical stability and adjustable pore structure showed great potential and broad application prospects in the field of CO2 adsorption. Future efforts should focus on exploring the large-scale preparation techniques of biomass carbon aerogels and their practical applications in complex industrial environments, promoting their transition from laboratory research to practical applications.

Key words: biomass, carbon aerogels, CO2 capture, adsorption, porous media
