ABSTRACT:
The present invention is directed to high activity titanium oxide DeNOx catalysts. In preferred embodiments, by depositing vanadium oxide on a titania supported metal oxide such as tungsten oxide, an improved catalyst may be generated. This catalyst may be used in the treatment of exhaust from sources such as automobiles and industrial plants.
