Efficient dehydration of the organic solvents through graphene oxide (GO)/ceramic composite membranes

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.
