▎ 摘 要
NOVELTY - A titanium dioxide/graphene composite material is prepared by heating graphite mixture with peroxide, adding water, performing ultrasonication, mixing with reducing agent aqueous solution and titanium salt precursor aqueous solution, and performing hydrothermal reaction in which reducing agent is hydrazine hydrate, phthalate diethylene glycol diacrylate, glucose, or ascorbic acid. USE - Preparation of titanium dioxide/graphene composite material (claimed). ADVANTAGE - Preparation process is simple. Product has high photocatalytic efficiency.
