▎ 摘　　要

NOVELTY - The preparation of three-dimensional rice-type titanium dioxide/graphene composite hydrogel involves using tetrabutyl titanate as titanium source, preparing tetrabutyl titanate alcohol solution, adding resulting tetrabutyl titanate alcohol solution to aqueous graphene oxide solution, mixing, adding sodium citrate to control growth of titanium dioxide and carrying out hydrothermal reaction. USE - Preparation of three-dimensional rice-type titanium dioxide/graphene composite hydrogel (claimed). ADVANTAGE - The method enables preparation of three-dimensional rice-type titanium dioxide/graphene composite hydrogel with high stability by simple and environmentally-friendly process.
