▎ 摘　　要

NOVELTY - Preparing Mxene-derived titanium dioxide nanosheet-graphene gel complex material comprises forming graphene oxide aqueous solution in aqueous solution, adding Mxene into the graphene oxide aqueous solution to obtain a first mixed solution, adding a reducing agent into the first mixed solution, forming a Mxene-graphene hydrogel in a water bath, adding the crystal plane control agent to water to obtain a second mixed liquid, placing the Mxene-graphene hydrogel in the second mixed solution, performing a hydrothermal reaction to obtain titanium dioxide nanosheet-graphene hydrogel, and freeze-drying to obtain TiO2 nanosheet-graphene aerogel complex material. USE - The complex material is useful in the field of photocatalysis (claimed). ADVANTAGE - The titanium dioxide nano-sheet has regular shapes, uniform sizes, and uniform crystal phases. The complex material macroscopic body is easy to separate; and enhances the material's utilization of visible light and electron transmission efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for Mxene-derived titanium dioxide nanosheet-graphene gel complex material.
