摘要
Mixed matrix membrane used to selective removal of CO2 was considered as an efficient solution to energy and environmental sustainability. In this study, a MMM that consists of amide functionalized porous coordination polymer filler（MIL-53-NH2） was successfully prepared, which sharply promotes the CO2/N2 selectivity from 44（neat polymeric membrane） to 75. Remarkably, the positive effect of amide group and nanochannel of MIL-53-NH2 filler was illustrated by decreased selectivity of the MMM with formic acid modified MIL-53-NH2 filler（MIL-53-NHCOH）.
