Abstract

This article describes the preparation of continuous metal-organic framework (MOF) Zn(bdc)(dabco)?_0.5 membranes on flexible polymer substrates using a radiation-induced method. The morphologies and structures of the membranes were investigated using X-ray diffraction,Fourier-transform infrared spectroscopy,and scanning electron microscopy. Their light hydrocarbon-adsorption properties were characterized using Brunauer-Emmett-Teller specific surface area measurements,density functional theory pore-size analysis,and single-component adsorption isotherms. The results indicated that the Zn(bdc)(dabco)_0.5 membranes exhibited higher adsorption for ethane and propane than for methane. Moreover,the Zn(bdc)(dabco)_0.5 membranes showed enhanced ethane/methane selectivity (reaching 11 at atmospheric pressure) and propane/methane selectivity (reaching 10 at atmospheric pressure). This study demonstrates the unique advantages of MOF membranes in the field of separation.
