摘要
阐述了丝光沸石(MOR)的结构及其吸附CO2机理以及合成技术进展,重点对通过简单物理化学处理、金属离子改性和后官能化的MOR吸附CO2的研究进展进行了综述,并介绍了 MOR在废气以及直接空气碳捕获工程中吸附CO2的应用情况.指出今后的研究方向是通过优化调整MOR框架、孔径分布以及组成或通过合成结合了不同特征结构的核壳沸石来实现对CO2吸附能力的提升.
Abstract
The structure of mordenite(MOR)and its adsorption mechanism of CO2,as well as the progress of its synthesis technology were described.The research progress of CO2 adsorption by MOR through simple physical and chemical treatment,metal ion modification and post-functionalization was reviewed.The application of MOR in CO2 ad-sorption in exhaust gas and direct air carbon capture engineering was introduced.It was pointed out that the future research direction was to improve the CO2 adsorption capacity by optimizing the MOR frame-work,pore size distribution and composition,or by synthesizing core-shell zeolites with different char-acteristic structures.
