NOVELTY - Preparation of multi-reactive metal/graphene composite hydrogen storage material involves preparing graphene oxide/active metal salt solution by liquid-phase generation method, self-assembling transition metal on surface of graphene oxide by liquid-phase self-assembly, reacting in hydrothermal reaction vessel, and carrying out high-temperature reduction under protective gas and reducing atmosphere. USE - Preparation of multi-reactive metal/graphene composite hydrogen storage material used for hydrogen storage system and solid propellant. ADVANTAGE - Preparation of multi-reactive metal/graphene composite hydrogen storage material having high hydrogen storage capacity of 6.2-7.3 wt.%.
