▎ 摘　　要

NOVELTY - Preparation of graphene/platinum nanocomposite aerogel material, involves mixing isopropanol solution of chloroplatinic acid hexahydrate with graphene oxide solution to obtain mixed solution, introducing nitrogen gas into mixed solution for 10-20 minutes, subjecting mixture to 60-cobalt irradiation at room temperature, washing and freeze-drying. USE - Preparation of graphene/platinum nanocomposite aerogel material (claimed). ADVANTAGE - The method enables preparation of lightweight graphene/platinum nanocomposite aerogel material with high dispersibility and high porosity, and does not require additional surfactant.
