Ultrathin, Molecular-Sieving Graphene Oxide Membranes for Selective Hydrogen Separation

Ultrathin, molecular-sieving membranes have great potential to realize high-flux, high-selectivity mixture separation at low energy cost. Current microporous membranes [pore size 2 /CO 2 and H 2 /N 2 mixtures, respectively, through selective structural defects on GO.
