Abstract

The invention discloses a photocatalyst added with nanoscale precious metals. The raw materials are as follows by weight: 10ml-20ml of 3%-5% nanoscale photocatalyst aqueous solution, 2-3 grams of iron, 1-2 grams of magnesium, and 2-3 grams of bentonite gram, use elemental iron and elemental magnesium as raw materials, the source of materials is wide, and the price is cheap. Use elemental iron and elemental magnesium to prepare nano-iron and nano-magnesium first, strictly control the proportion of each component, optimize the raw material formula, and adopt the method of water bath heating. Strictly control the temperature and time in the preparation process to ensure product quality, so that the produced photocatalyst with nano-scale precious metals can not only play a catalytic role under the condition of ultraviolet light, but also have a good catalytic effect under the condition of infrared light and other visible light. The catalytic effect is simple, the preparation process is simple, and the production cost is low.

Description

Technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a photocatalyst added with nano-level precious metals and a preparation method thereof. Background technique [0002] Photocatalyst is a nano-level metal oxide material (titanium dioxide is more commonly used). It is coated on the surface of the substrate, and under the action of light, it produces a strong catalytic degradation function: it can effectively degrade toxic and harmful gases in the air; it can effectively kill It kills a variety of bacteria, and can decompose and harmlessly treat the toxins released by bacteria or fungi. It also has the functions of deodorization and anti-fouling. Photocatalyst [Photocatalyst] is a compound word of light [Photo=Light] + catalyst (catalyst) [catalyst]. Photocatalyst is a general term for photo-semiconductor materials with photocatalytic function represented by nano-scale titanium dioxide. It is currently the most ideal mater...
