▎ 摘　　要

NOVELTY - Preparation of a tin/graphene nanocomposite material comprises adding 5-27.5 mg/mL polyvinylpyrrolidone ethanol solution, 5-12 mg/mL stannous chloride dihydrate solution, and 3 mg/mL graphene oxide ethanol solution to a reactor, and uniformly mixing in an argon atmosphere; adding 5-27.5 mg/mL sodium borohydride solution, uniformly stirring at room temperature, performing a reduction reaction at 90-180 degrees C for 6 hours, washing, and drying. USE - Method for preparing a tin/graphene nanocomposite material. ADVANTAGE - The method is simple and environment-friendly. The nanocomposite material has high degree graphene oxide reduction.
