温室效应日渐显著，CO2的捕集与储存（CCS）是一种潜力巨大的减排措施，其中吸附法捕集CO2是最有前景的技术之一。多孔固体材料因其优异的CO2吸附性能备受关注。针对吸附法脱除CO2的研究进行综述，介绍了五种不同的吸附材料，总结了影响它们吸附CO2的主要因素，以及改性后材料的吸附性能。结果表明，温度、压强、孔结构的改变会影响材料的物理吸附性能；还原改性、氧化改性和金属离子负载改性能够改变材料表面官能团的种类或者数量，提高了材料的CO2吸附性能。

As the greenhouse effect becomes gradually significant, CO2 capture and storage (CCS) has turned into a potential emission reduction measure, and the adsorption method of CO2 capture is one of the most promising technologies. Porous solid adsorbents have attracted widespread attention due to their excellent CO2 adsorption performance. This review focused on the research of CO2 removal by adsorption. Five different adsorption materials were introduced, and the main factors affecting CO2 adsorption were summarized, as well as the adsorption performance of modified materials. The results show that the changes of temperature, pressure, and pore structure can affect the physical adsorption properties of the materials; reduction, oxidation, and metal ion loading modification can improve the CO2 adsorption performance by Changing the type or number of functional groups on the surface of the material.
