Preparation method of graphene/nickel-aluminum bi-metal hydroxide composite material and application thereof

The invention discloses a preparation method of a graphene/nickel-aluminum bi-metal hydroxide composite material and an application thereof, belonging to the technical field of electrochemistry. The preparation method comprises the following steps of: preparing a mixed solution by a stripping enhancer, oxidized graphene and deionized water, dispersing the mixed solution by ultrasonic wave; decompressing and filtering the mixed solution to obtain a filtering cake, and arranging the filtering cake into a household microwave oven to radiate; placing a graphene filtering cake into a tubular furnace, charging Ar/H2 mixed gas, and executing high-temperature thermal cracking; and adding an alkali source compound, nickel and aluminum salt precursors, a medium regulating agent and the deionized water to prepare a reactant mixing solution, and transferring the reactant mixing solution to a high-pressure reaction kettle to carry out a hydrothermal reaction, and finally obtaining the graphene/nickel-aluminum bi-metal hydroxide composite material. According to the preparation method of the graphene/nickel-aluminum bi-metal hydroxide composite material, disclosed by the invention, toxic chemical agents are not used at two steps of reduction of the graphene, thus damage on the health of a human body and environmental pollution because a large number of harmful chemical agents such as hydrazine hydrate and the like are taken as a strong reducing agent in a chemical reduction method can be eliminated fundamentally.
