Title:
二機能酸化マンガン/二酸化チタン光触媒/熱触媒
Document Type and Number:
Japanese Patent JP2006528055
Kind Code:
A
Abstract:
A manganese oxide/titanium dioxide photocatalytic/thermocatalytic coating simultaneously oxidizes volatile organic compounds and decomposes ozone that adsorb onto the coating into water, carbon dioxide, and other substances. The manganese oxide is nano-sized. When photons of the ultraviolet light are absorbed by the manganese oxide/titanium dioxide coating, reactive hydroxyl radicals are formed. When a contaminant is adsorbed onto the manganese oxide/titanium dioxide coating, the hydroxyl radical oxidizes the contaminant to produce water, carbon dioxide, and other substances. Manganese oxide lowers the energy barrier required for ozone decomposition, decomposing the ozone to molecular oxygen. Therefore, the manganese oxide/titanium dioxide coating can also simultaneously decompose ozone to oxygen.
