Amine-functionalized MOFs@GO as filler in mixed matrix membrane for selective CO2 separation

UiO-66-NH2@GO nanoparticles were synthesized by growing UiO-66-NH2 on graphene oxide (GO) nanosheets. The obtained nanoparticles were incorporated in polyimide (PI) matrix to improve the CO2 separation performance. The crystalline structure, interaction between UiO-66-NH2 and GO and the dispersion of UiO-66-NH2@GO were characterized by various techniques. Owning to the interaction between UiO-66-NH2 and GO, UiO-66-NH2 nanocrystals were...
