Abstract: Abstract: Ceramic membrane has high permeation rate of hydrogen and chemical stability. Al2O3 indicates stable at high temperature and a relatively large surface area. In addition, Al2O3 of porous is used as hydrogen separation membranes support, because of the high hydrogen permeability based on Knudsen diffusion mechanism. In this work, metal alkoxides as starting materials was used Aluminum isopropoxide powder. Then CeO2 as catalyst at the partial oxidation and Graphene Oxide as electrical conductivity are added, Al2O3–CeO2–Graphene oxide (ACG) composites are synthesized by sol–gel process. ACG membrane was fabricated type of disk by Hot Press Sintering. A synthesized ACG composite material was characterized by EDS, SEM, TG/DTA, XRD, BET. The hydrogen permeation property of ACG membrane was measured by Sievert's type hydrogen permeation membrane equipment. The hydrogen permeability of ACG membranes was examined at RT-673 K under increasing pressure. Results, hydrogen permeability was obtained to 2.62 × 10−7 mol/ms Pa1/2 at 673 K under 0.3 MPa.
