▎ 摘 要
NOVELTY - A graphene-tin dioxide nanoparticle composite material is prepared by dissolving graphite oxide and tin chloride in water, separating, washing the obtained product, and heat-processing under oxygen free environment. USE - Method for preparing graphene-tin dioxide nanoparticle composite material (claimed). ADVANTAGE - The method has simple preparation and low cost, reduces the use of chemical reagent, and is green and environment-friendly.
