摘要
A supported graphene oxide membrane is endowed with selective function for olefins by a cation intercalation method. The metal-cation fixed GO membrane exhibits a high propane to propylene ideal selectivity of 1817 for single gas and a separation factor of 7.1 for binary mixtures with fast gas permeance in the order of 10(-7) mol m(-2) s(-1) Pa-1 and reliable permeation stability.
