▎ 摘　　要

NOVELTY - The preparation method of graphene-( gamma )-molybdate bismuth nanocomposite material involves (1) thermally reacting graphene, bismuth nitrate and ethylene glycol together in a solvent, filtering, washing and drying to obtain graphene-ethylene glycol bismuth composite material, (2) uniformly dispersing the obtained composite in an aqueous sodium molybdate solution, adjusting pH of the resulting solution to 0-3, subjecting to hydrothermal reaction, filtering, washing and drying. USE - Preparation of graphene-( gamma )-molybdate bismuth nanocomposite material used as photocatalytic material (claimed). ADVANTAGE - The method enables preparation of graphene-( gamma )-molybdate bismuth nanocomposite material with high photocatalytic activity by simple process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) graphene-( gamma )-molybdate bismuth nanocomposite material; and (2) application of graphene-( gamma )-molybdate bismuth nanocomposite material as photocatalytic material.
