▎ 摘　　要

NOVELTY - A reduction graphene oxide/titanium dioxide nanocomposite material is prepared by preparing graphene oxide, adding into conical bottle, adding anhydrous ethanol, putting into ultrasonic cleaner, ultrasonically processing, adding nanotitanium dioxide, continuously ultrasonically processing to obtain graphene oxide/titanium dioxide anhydrous ethanol dispersion liquid, placing into dark tank, stirring, photocatalytic reduction processing using UV mercury lamp irradiation, and drying. USE - Method for preparing reduction graphene oxide/titanium dioxide nanocomposite material (claimed). ADVANTAGE - The method has efficient reduction, and plays graphene oxide and nanotitanium dioxide synergy effect.
