摘要：
Porous Al2O3 tube supported GO composite membranes with submicron thickness and improved mechanical strength were fabricated via a filter-pressing deposition method. High separation performance (flux, selectivity and stability) was achieved in the pervaporation of ethanol, n-propanol, iso-propanol, ethyl acetate and butanol isomers aqueous mixture.
