Graphene oxide (GO) laminate membranes of controlled interlayer spacing were synthesized for the investigation in H2/CO2 separation. The interlayer distance of GO flakes was tuned by crosslinking and intercalation of La3+ or Co2+ cations between GO layers. Investigation via field-emission scanning e...
