▎ 摘 要
NOVELTY - Metal or metal ion modified carbon-based ozone activation catalyst is formed by supporting metal or metal salt on inside and surface of carbon carrier, and it is used to adsorb and catalyze decomposition of portion of ozone and using the hydrogen peroxide generated in the internal and surface decomposition of the carbon carrier by metal or metal ion to degrade organic pollutant and eliminate secondary pollution. USE - Metal or metal ion modified carbon-based ozone activation catalyst used for for oxidizing and decomposing volatile organic compound (claimed). ADVANTAGE - The catalyst has quickly eliminate organic pollutants in a short time through the mode of first decomposing ozone and degrading pollutant and the mode of decomposing ozone while degrading pollutantsand good service life and regeneration ability, and good application prospect in the treatment of indoor air pollution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a metal or metal ion modified carbon -based ozone activation catalyst, which involves: a).mixing the metal salt with deionized water at room temperature;b).stirring until dissolving to obtain first solution;c).adding carbon carrier to the obtained first solution;d).stirring to obtain a suspension;e).separating the suspension into solid and liquid to obtain a metal ion modified carbon-based ozone activation catalyst;f).performing reduction treatment of the metal ion-modified carbon-based ozone activation catalyst to obtain the metal-modified carbon-based ozone activation catalyst.
