Graphitic Carbon Nitride–Graphene Oxide Hybrid Membranes for Hydrogen Purification

Graphitic carbon nitride-graphene oxide (g-C3N4/GO) composite membranes were fabricated via filtrating g-C3N4 and a small amount of GO on a porous polymer support. GO nanosheets were incorporated in g-C3N4-based membranes to prevent interedge defects or voids from forming. Accordingly, the selective...

Description
Summary:Graphitic carbon nitride-graphene oxide (g-C3N4/GO) composite membranes were fabricated via filtrating g-C3N4 and a small amount of GO on a porous polymer support. GO nanosheets were incorporated in g-C3N4-based membranes to prevent interedge defects or voids from forming. Accordingly, the selective molecular sieving pores and interlayer channels of g-C3N4 can effectively separate H2 molecules from larger gas molecules (CH4, N2, O2, and CO2). When the GO weight loading reaches 5%, the g-C3N4/GO composite membrane shows an enhanced H2/CO2 separation performance with a H2 permeance of 3.66 × 10–6 mol m–2 s–1 Pa–1 (H2/CO2 ideal selectivity: 179.6).
