Abstract

The invention provides a composite material of anatase titanium dioxide and gold nanofilm and a preparation method thereof. The gold nanofilm is a gold nanofilm that has been irradiated by ultraviolet rays, and anatase titanium dioxide dispersion is dripped on it. The gold nanofilm has better thermal conductivity and electrical conductivity, and has good toughness. In addition, titanium dioxide particles and gold nanoparticles generate plasmon resonance, which improves photocatalytic activity, so it is very suitable for water purification, air purification, etc.

Description

technical field

[0001] The invention relates to anatase titanium dioxide photocatalyst technology, in particular to a composite material of anatase titanium dioxide and gold nano film and a preparation method thereof. Background technique

[0002] Anatase titanium dioxide, as the most representative photocatalyst material, is a nano-scale photo-semiconductor material with photocatalytic function. The photocatalyst is coated on the surface of the substrate, and under the action of ultraviolet rays, it can produce a strong catalytic degradation function: it can effectively degrade toxic and harmful gases in the air; it can effectively kill a variety of bacteria and decompose the toxins released by bacteria or fungi And harmless treatment; at the same time, it also has the functions of removing formaldehyde, deodorizing, anti-pollution, and purifying air. Photocatalyst is currently the safest and cleanest environmental purification material in the world. It is widely used in E...
