▎ 摘　　要

NOVELTY - Manufacture of graphene-based hydrogen storage material involves mixing 20-50 wt.% graphite oxide, transition metal precursor and 80-50 wt.% melamine in aqueous medium, drying at 50-60 degrees C in vacuum oven, obtaining nanocomposite and placing nanocomposite under focused sunlight using convex lens. The graphene-based hydrogen storage material is transition metal-containing nitrogen-doped graphene hybrid material. USE - Manufacture of graphene-based hydrogen storage material is used for hydrogen-fuelled vehicle and portable electronics. ADVANTAGE - The method efficiently provides graphene-based hydrogen storage material having excellent hydrogen adsorption-desorption characteristics by economical process.
