英文摘要CO2 is the main component of the greenhouse gases. Concerns of global warming have drawn unprecedented public attention to the issue of CO2 emissions and resulted in a number of initiatives to reduce CO2 emissions. Now the selective CO2 capture over CH4 in porous materials, especially at ambient temperature and pressure, still remains challenging[1-3]. Here, we report the synthesis of four new porous coordination polymers constructed using chromium(III) chloride hexahydrate and four dicarboxylic acids, respectively, under solvothermal conditions. These materials were characterized by SEM, XRD, IR, and nitrogen physisorption. CO2 and CH4 sorption capacities of the four materials were measured by using volumetric gas adsorption. These materials exhibited high selective CO2 capture over CH4 and proved superior to those reported for most MOFs and ZIFs under similar conditions[2-3]. The chromium(III)-based coordination polymers are a promising candidate for CO2 capture at 273 K.; CO2 is the main component of the greenhouse gases.
