The role of ozone decomposition catalyst and preparation method

Ozone catalyst is a material with the ability to catalyze ozone decomposition reaction, it can effectively decompose ozone into oxygen and free radicals, play the role of purifying ozone in the environment, it is widely used in air purification, water treatment, organic waste gas treatment and other environmental fields. Ozone catalyst adsorbed ozone molecules through the active site on the catalyst surface, and caused it to react, decompose into oxygen and free radicals; Among them, free radicals have strong oxidation and can react with harmful substances to transform them into harmless substances, thus playing a role in purifying the environment. Its preparation methods are mainly physical methods and chemical methods.
The physical method is to change the structure and morphology of the catalyst by physical means to improve its catalytic performance. Common physical methods include heat treatment, solvothermal method, coprecipitation method, etc. Chemical method is the use of chemical reaction to synthesize ozone catalysts, so as to obtain high catalytic performance of materials, common chemical methods include sol-gel method, deposition method, hydrothermal method and so on.
