摘要：
Metal-organic frameworks (MOFs) are widely used in the field of CO2 adsorption and separation due to their high specific surface area, high selectivity, structural tunability and renewability. Firstly, the advantages and disadvantages of MOFs and other CO2 treatment methods and CO2 adsorption materials were compared, and the unique advantages of MOFs were obtained. According to the structure and chemical characteristics of MOFs, the physical and chemical adsorption mechanism of CO2 was summarized, and the basic principle of MOFs as CO2 adsorption materials was deeply revealed. On this basis, in view of the defects that still existed in the performance and structure of MOFs and needed to be improved, the research progress of the functionalization modification of MOFs (multi-metal doping, multimaterial composite, construction defects, amine functionalization, polar group functionalization, etc.) and the CO2 adsorption performance of modified MOFs were summarized by comparing the performance of different types of MOFs. By evaluating the advantages and disadvantages of these modification methods and considering their applicability and economy, the aim was to find a better modification method for MOFs. The future development of MOFs modification required further in-depth research on the loading of multiple functional groups, greening of synthesis and loading methods and the ratio of surface area to binding sites. Additionally, the advancement of characterization methods for modifications was a key element in the future development of MOFs modification. © 2024 Chemical Industry Press Co., Ltd..
