Abstract
The present invention generally relates to supported mono charged cation delta manganese dioxide hydrate having a noble metal on the surface thereof, and to the use thereof for low temperature oxidation of volatile organic compounds (VOCs), particularly oxygen-containing VOCs. The present invention further relates to the use of the supported catalysts to reduce the amount of VOCs present in waste gases produced by processes such as baking, brewing, and flexographic printing. Catalysts prepared from the supported manganese-containing catalysts have increased resistance to poisoning in the presence of catalyst contaminants, e.g., sulfur containing compounds.
