Problems solved by technology

[0003] Pure nano-titanium dioxide is in the form of simple powder, which is less practical, because it will disappear when the wind blows, so it is often made into a mixed liquid state with a binder added

Embodiment Construction

[0033] See figure 1 Shown, the preparation method of the composite material of the anatase type titanium dioxide of the specific embodiment of the present invention and gold nano film, comprises the steps:

[0034] First, making gold nano film;

[0035] Second, the gold nano film is irradiated with ultraviolet light, and the time length is T;

[0036] Third, prepare anatase titanium dioxide dispersion;

[0037] Fourth, the anatase titanium dioxide dispersion liquid is dropped on the gold nano film.

[0038] Among them, the gold nano film is made by dropping a chloroform solution containing gold nanoparticles on the water surface to form a Langmuir film independently. For details, please refer to figure 2 shown.

[0039] First, fill the sink with distilled water. Preferably, the sink can be wiped with distilled chloroform first.

[0040] Secondly, the gold nanoparticles are dissolved in distilled chloroform. Preferably, the gold nanoparticles are stored at low temperatur...

Abstract

The invention provides a composite material of anatase titanium dioxide and a gold nano-film and a preparation method thereof. The gold nano-film is irradiated through ultraviolet rays, and ananatase titanium dioxide dispersion liquid is dropped to the gold nano-film. The gold nano-film has better heat conductivity and electrical conductivity as well as good toughness. Moreover, titanium dioxide particles and gold nanoparticles generate plasma resonance, so that the activity of a photocatalyst is improved. Therefore, the composite material is quite suitable for water purifying treatment, air purification and the like.

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...
