The invention discloses a supported metal organic skeleton/graphene oxide hydrogen storage material and a preparation method thereof. The hydrogen storage material is formed by steeping palladium metal in a metal organic skeleton/graphene oxide carrier, wherein the loading capacity of the palladium metal is 1.0-5.0% of the mass of the carrier; and the metal organic skeleton is ZIF-8. The preparation method comprises the following steps: firstly heating reactants of dissolvable zinc salt, 2-methylimidazole and graphene oxide to prepare a metal organic skeleton/graphene oxide carrier material, and then loading dissolvable palladium salt in the metal organic skeleton/graphene oxide carrier to obtain the supported metal organic skeleton/graphene oxide hydrogen storage material under the condition of existence of a reductant and a dispersant by adopting an excessive steeping method. The supported metal organic skeleton/graphene oxide hydrogen storage material has good hydrogen storage performance at room temperature, and the process is simple.
