Embodiment 1

[0050] A slurry of a patternable environmental catalytic material, the preparation method of which is as follows:

[0051] (a) Preparation of titanium dioxide (TiO 2 ) slurry (grinding method): Measure 5mL small molecule organic acid-formic acid and 20mL 0.01-0.5M silver nitrate solution to mix, add 1-10 drops of surfactant polyethylene glycol octylphenyl ether (Triton X -100), stirred at room temperature for 10-15 minutes to obtain a titanium dioxide slurry; weigh 1-3g of commercially available TiO 2 Powder-Degussa nano-titanium oxide (DegussaP25), while grinding, drop 5mL of the titanium dioxide slurry grinding solution prepared above, and the grinding time is 30 minutes, until a uniformly mixed white slurry is formed to obtain TiO 2 slurry;

[0052] (b) Preparation of alumina (Al 2 o 3 ) slurry (sol-gel method): Weigh 6.72g aluminum nitrate or its crystalline hydrate and dissolve it in 50-100mL water, add 0.48 aluminum foil, and reflux in the reflux device for 100 minut...

Embodiment 2

[0068] Preparation steps are the same as example 1, the difference is: prepare TiO 2 In the process of slurry, measure 8mL of small molecular organic acid-formic acid and mix it with 25mL of water.

Embodiment 3

[0070] Preparation steps are the same as example 1, the difference is: prepare TiO 2 During the slurry process, add 1-10 drops of surfactant as alkylphenol polyoxyethylene ether (OP-10).

Abstract

The invention relates to nano-sized patternable environmental catalysis materials (metal / semiconductor catalyst / adsorbing material) and a size preparation method thereof, belonging to the field of inorganic nano materials. The product surface is in a porous structure with uniform granularity; and the product has strong light absorbing ability, and can express a certain methanal degrading ability at the dark and illumination condition, and the performance of the Ag / TiO2 / AlO3 is the highest. The prepared pattern has better visual effect; and the selectivity of a substrate is wide, and the substrate can be a high temperature resistant material, such glass, ceramic tile, stone, metal, ceramics and the like, and has wide application. The invention has simple operation and good repeatability, has low requirement on the complexity of environment and equipment, integrates practicability and artistry into a whole, purifies the environment, brings physical and mental pleasure, and is suitable for large-scale development and production so as to cope with the indoor environment pollution on the rise.

Description

technical field [0001] The invention relates to a nanometer-sized patternable environmental catalytic material (metal / semiconductor catalyst / adsorption material) and a preparation method for its slurry, belonging to the field of inorganic nanometer materials. Background technique [0002] Formaldehyde is an important organic raw material, which is widely used in synthetic adhesives and exists in building decoration materials and daily necessities. Formaldehyde is extremely toxic and can damage the liver, skin, immunity, endocrine, and nervous system of the human body to a certain extent. It is one of the potential mandatory mutants and has been identified as one of the carcinogenic and teratogenic substances by the World Health Organization. The standard for formaldehyde content in the indoor air stipulated by the Ministry of Health of my country is 0.08mg / m 3 , but incidents of excessive formaldehyde occurred frequently across the country [Research on Formaldehyde Pollutio...
