Fabrications and evaluations of hydrogen permeation on Al2O3/CeO2/graphene (ACG) composites membrane by Hot Press Sintering (HPS)

▶ We synthesized Al2O3-CeO2-Graphene oxide (ACG) composites by sol-gel method. ▶ ACG membrane was fabricated type of disk by Hot Press Sintering (HPS). ▶ Hydrogen permeability of ACG membrane was in proportion with temperature and pressure. ▶ CeO2 and Graphene oxide as catalysts had positive impact on hydrogen permeation.
