摘要：
Continuous ZIF-8 membranes effectively separated air/Xe gas mixtures. These membranes showed air permeances as high as 3.94 x 10(-8) mol m(-2) s(-1) Pa-1 and separation selectivities as high as 12.4 for an air/Xe molar feed composition of 9:1. These membranes separated air from Xe via molecular sieving, preferential adsorption, and diffusivity differences.
