Description

technical field [0001] The invention relates to the technical field of photocatalysts, in particular to a preparation method of a novel visible light photocatalyst. Background technique [0002] Photocatalyst, also known as photocatalyst, is a general term for the preparation method of a new type of visible light photocatalyst, represented by nanoscale titanium dioxide, which has photocatalytic function. The representative photocatalyst material is titanium dioxide, which can produce strong oxidation under light irradiation. and can be used to decompose organic compounds, some inorganic compounds, bacteria and viruses, etc. In daily life, photocatalyst can effectively degrade toxic and harmful gases in the air such as formaldehyde, etc., and efficiently purify the air. At the same time, it can effectively kill a variety of bacteria, and can decompose and harmless treatment of toxins released by bacteria or fungi. [0003] The current common photocatalysts have low stability...
