英文摘要	ZIF-8 membranes were prepared on alpha-alumina substrates in a urea/choline chloride (ChCI) based deep eutectic solvent using an in situ method. The synthesized ZIF-8 membranes were characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The effects of the concentration of the reaction solution and the cooling rate on ZIF-8 membrane synthesis were investigated. The results indicate that increasing the concentration of the reaction solution and reducing the cooling rate are beneficial for synthesizing continuous ZIF-8 membranes. A continuous and compact ZIF-8 membrane with a thickness of about 6 mu m was obtained on the substrate by optimizing the synthetic conditions. The single gas permeation and binary mixture gas separation performances of the ZIF-8 membrane prepared under the optimized synthetic conditions were determined using the Wicke-Kallenbach technique. For equimolar gas mixtures at room temperature (293 K), the separation factors for H-2/CO2, H-2/O-2, H-2/N-2, and H-2/CH4 were 7.4, 5.2, 9.1, and 13.8, respectively. All the separation factors exceed the corresponding Knudsen diffusion coefficients, indicating that the ZIF-8 membrane displays molecular sieving performance.
