▎ 摘 要
NOVELTY - A tin dioxide-graphene composite material is prepared by dissolving graphene oxide and tin chloride in water, separating, rinsing, re-dispersing obtained product in water, and adding reducing agent. USE - Method for preparing tin dioxide-graphene composite material (claimed). ADVANTAGE - The method is simple and inexpensive, avoids high temperature heat processing process, and is energy-saving and environment-friendly.
