The intensification of global greenhouse effect and the proposal of carbon peak carbon neutralization further push the capture and storage of carbon dioxide (CO2) to a climax. The proposal of carbon peak and carbon neutralization further becomes the focus of low-carbon emission reduction. Liquid absorbents are highly volatile and prone to corrosion of equipment, which creates conditions for the development of adsorbents. In order to study the adsorbent with excellent performance, a novel high CO2 selective adsorbent ZIF-N-0.75 was synthesized, which made the adsorption selectivity of carbon dioxide up to 16.0568. ZIF-67 and ZIF-N-0.75 were synthesized by solvothermal method, and the pore structure of adsorbent was regulated. Ionic liquid is a new type of carbon dioxide absorbent, which has the advantages of low volatility and low corrosion. And ionic liquid absorption capacity is very large. In this paper, a new type of adsorbent is synthesized by combining absorbent and adsorbent to optimize the performance of adsorbent. In this study, ZIF-N and ZIF-B were synthesized by impregnating ZIF-67 with ionic liquid (tetramylammonium glycine ([N1111][Gly]) and 1-butyl-3-methylimidazolium L lysine ([Bmim][Lys]). The experimental results show that the new adsorbent after impregnation improves the adsorption selectivity of CO2 from 10.294 to 23.087. This provides a good idea for CO2 capture. %K CO2捕集,CO2吸附剂,吸附选择性,离子液体
