Cu-based metal-organic framework with dual open metal sites for efficient separation of CO2 from flue gas
Excessive carbon dioxide (CO2) emissions from flue gases intensify the greenhouse effect. Exploring porous adsorbents with high CO2/N2 selectivity is of great significance to reducing the CO2 content in flue gases. Herein, we report a novel PtS-type metal-organic framework (MOFs), termed ZSTU-21, with narrow pore size and excellent CO2/N2 separation performance with dual open copper sites. At 298 K, ZSTU-21 exhibits a CO2 uptake capacity of 62 cm3 g−1 and a high selectivity of 105 for CO2/N2 (CO2/N2 = 15/85, v/v). Multicomponent adsorption breakthrough experiments further verified the superior performance of ZSTU-21 MOF in CO2/N2 separation. Moreover, the synthesis of ZSTU-21 MOF can be carried out under mild experimental conditions at room temperature, making the process simple and cost-effective, thus laying a solid foundation for its widespread application in CO2/N2 separation.
