二氧化碳吸附材料研究新进展

Recent Research Progresses on the CO₂ Adsorption Materials

CO2是导致温室效应的主要气体,减少其排放是遏制全球气候变暖的关键,CO2的捕集与封存对于缓解温室效应具有重要意义;而捕集与封存的关键是寻求高吸附量、高选择性、热稳定性好且循环性能良好的吸附剂。近些年来一些多孔材料如活性炭、沸石分子筛、金属有机骨架材料被广泛应用于CO2吸附。本文介绍了CO2捕集方法及各种多孔材料的CO2吸附性能,重点介绍了密胺基微孔有机聚合物(MBMPs)。MBMPs由于其具有较高的比表面积、合成方法多样、容易功能化修饰等优点,在气体的存储与分离方面具有广阔应用前景。

CO2 as the main greenhouse gas, the reduction of its emission is the key to curb global warming. CO2 capture and sequestration (CCS) is of significance for the mitigation of greenhouse effect. The key of CCS is seeking for the adsorbents with high adsorption capacity, high selectivity, good thermal stability, and good recyclability. In recent years, some porous materials such as activated carbon, zeolite molecular sieves, and metal organic polymer materials have been widely applied to CO2 adsorption. This paper firstly gives an overview introduction of the methods of CO2 capture as well as some porous materials as CO2 adsorbents. Afterwards, melamine based microporous polymers (MBMPs) are highlighted. Due to the advantages of the high specific surface area, the diversity of the synthetic methods, the easy functionalization, etc., MBMPs show a broad prospect of the application in gas storage and separation.
