▎ 摘　　要

NOVELTY - Preparing graphene-zinc oxide nanocomposite material involves dissolving solid graphene oxide in water to obtain graphene oxide aqueous solution and then dissolving zinc sulfate in the graphene oxide aqueous solution to obtain graphene oxide-zinc sulfate mixed solution. The obtained solution is mixed and dried to obtain graphene oxide-zinc sulfate solid mixture. The solid mixture is sintered in a sealing device under inert gas and then the sintered material is heated in a tubular heating furnace. The heated material is cooled to room temperature and sintered to obtain the desired product. USE - Method for preparing graphene-zinc oxide nanocomposite material used in photoelectrochemical detection of acetamiprid (claimed), photoelectrochemical sensor, battery materials and photocatalytic field. ADVANTAGE - The method enables to prepare graphene-zinc oxide nanocomposite material in simple manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using graphene-zinc oxide nanocomposite material, which involves: (A) adding graphene-zinc oxide nanocomposite material with dimethylformamide dispersion liquid; (B) painting the obtained liquid on the electric conduction glass surface; and (C) drying the painted material and then painting desired articles.
