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...
