Abstract
The present invention provides a variety of thermal catalytic methods for the conversion of NO and other NO.sub.x compounds into environmentally compatible products such as molecular nitrogen, molecular oxygen, and carbon dioxide. The catalysts employed are able to remove NO in substantial percentage quantities over a wide temperature range of 0.degree.-1,000.degree. C. and a preferred temperature of 100.degree.-800.degree. C. both in the presence or in the absence of chemical reducing agents.
