Abstract

The invention discloses a super-thin-wall honeycomb-shaped structure titanium dioxide nano material and a preparation method thereof. The super-thin-wall honeycomb-shaped structure titanium dioxide nano material is of a relatively uniform layered structure, the thickness of a nanosheet is relatively small, gaps are formed among layered nanosheets, specific surface areas, specific surface energy, flame retardancy, conductivity, heat conduction coefficients, impact strength and electron migration capabilities can be remarkably improved, according to the preparation method, a titanium dioxide film layer grows from titanium dioxide gel on the surface of a carbon fiber substrate and a two-dimensional titanium dioxide nano structure layer of which the gap sizes and morphology can be controlled is prepared on a titanium dioxide nano seed layer, defects that a conventional nanosheet is relatively low in generation rate, large in thickness, complex in process and the like can be overcome, the production process is simple, reaction conditions are gentle, the preparation time is short, and further, the industrial application of a titanium dioxide nano-structure material can be accelerated.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to an ultra-thin-wall honeycomb structure titanium dioxide nanomaterial and a preparation method thereof. Background technique [0002] Photocatalytic technology driven by solar energy is an ideal technology for clean energy production and environmental pollution control. Functional nanomaterials with excellent photoelectric properties play a vital role in photoelectrochemical technology.
