methods of MOF membrane preparation require multiple steps and high-pressure conditions. In this study, a reliable one-step interfacialsynthesis method under atmospheric pressure has been developed to prepare zeolitic imidazolate framework-8 (ZIF-8) membranes supported on porous α-Al2O3 disks.

Carbon dioxide (CO2) is one of the major greenhouse gases emitted through human activities contributing to global climate change. According to United States Environmental Protection Agency (US EPA), CO2
, the interfacialsynthesis method confines the coordination of the MOF to the solvent interface, which ensures good control over MOF nucleation and growth processes [37][38]. Consequently, it is a promising approach to synthesize a defect-free MOF film. In comparison, the counter-diffusion method
