Abstract
A method for catalytically reducing nitrogen oxide compounds (NO, defined as nitric oxide, NO, +nitrogen dioxide, NO) in a gas by a material comprising a base metal consisting essentially of CuO and Mn, and oxides of Mn, on an activated metal hydrous metal oxide support, such as HMO:Si. A promoter, such as tungsten oxide or molybdenum oxide, can be added and has been shown to increase conversion efficiency. This method provides good conversion of NOto N, good selectivity, good durability, resistance to SOaging and low toxicity compared with methods utilizing vanadia-based catalysts.
