摘要
功能化多孔材料拥有优越的CO_2吸附和存储性能,在燃煤电厂、玻璃炉窑、水泥厂、钢铁厂等高耗能工矿企业采用CO_2吸附技术,对CO_2减排、减缓温室效应具有重要意义。随着研究的不断深入,新型CO_2吸附材料呈现出廉价、易获取、高吸附率等趋势,当前研究重点集中在介孔硅、金属有机框架、沸石、活性炭、聚合物等的表面功能化。总结了上述典型吸附剂功能化的最新成果,重点介绍多孔吸附材料的功能化方法、吸附机理与吸附动力学的研究进展,并提出多孔材料对CO_2的吸附分离的研究空间和发展趋势。
Functional porous material has excellent adsorption and storage performance. CO_2 adsorption technique plays a significant role in controling the greenhouse effect and reduceing CO_2 emissions for coal-fired power plant,glass kiln,cement plant and steel plant. Novel CO_2 adsorbents were endowed with the characteristic as low cost,good accessibility,and high adsorption rate. Present research focused on the surface functionalization of porous silica,metal organic frameworks,zeolite,activated carbon and polymer materials. The paper summariezd the latest achievements on representative adsorbents functionalization,and also introduced progresses on functionalization protocols,adsorption mechanism and kinetics of porous adsorbents. Moreover,the future research space and development trend of porous materials for CO_2 adsorption were proposed.
