Abstract

The invention belongs to the technical field of materials, and discloses multilayer-graphene-carried titanium dioxide-ferrotitanium bimetal nanoparticles and a preparation method thereof. The preparation method comprises the following steps: carrying out ultrasonic oscillation in a DMF (N,N-dimethylformamide) solvent to generate a multilayer graphene DMF solution, carrying out hydrolysis reaction on tetrabutyl titanate to generate a titanium dioxide nano colloid, drying to obtain a dried multilayer-graphene-carried titanium dioxide nano colloid, heating to obtain multilayer-graphene-carried titanium dioxide nanoparticles, and preparing the multilayer-graphene-carried ferrotitanium bimetal oxide nanoparticles on such basis. The size of the prepared nano titanium dioxide particles on the graphene surface is less than 20nm; and the particles are distributed uniformly and have gaps, thereby providing space for depositing other oxide nanoparticles on the graphene surface. The multilayer-graphene-carried ferrotitanium bimetal oxide nanoparticles have the advantages of favorable particle crystallinity, small particle size and larger specific area.
