A photocatalyst is also called photocatalysis. Simply, a photocatalytic material undergoes light irradiation and does not change itself but can promote other substances to undergo a chemical reaction. There are many examples of photocatalyst reactions around us. The most typical is The chlorophyll, which plays the most important role in photosynthesis of plants, is a photocatalyst. Photocatalysts will produce photocatalytic reactions similar to photosynthesis under the irradiation of light, producing free hydroxyl and active oxygen with strong oxidation ability. They have a strong photoredox function and can oxidize and decompose various organic compounds and parts. Inorganic substances, which can damage the cell membrane of bacteria and proteins that solidify the virus, can kill bacteria and break down organic pollutants. Quickly decompose formaldehyde, benzene and ammonia in the air into non-toxic and harmless carbon dioxide and water. The main component of the photocatalytic materia...
