▎ 摘  要

NOVELTY - A nano-titanium dioxide/graphene composite hydrogel preparation method involves adding a nano-titanium dioxide into a graphite oxide aqueous solution containing reducing agent at room temperature to obtain a mixture. The mixture is subjected to ultrasonic dispersing at room temperature to obtain a precursor solution. The precursor solution is reacted for 8-16 hours to obtain a product. USE - Method for preparing nano-titanium dioxide/graphene composite hydrogel. ADVANTAGE - The method enables preparing nano -titanium dioxide/graphene composite hydrogel with better photo-catalysis performance, large ratio surface area, chemistry stability, high conductivity and high graphene reduction degree in a simple and rapid manner, without heating process, and enables achieving industrial production.
