Abstract
A method is provided for the photopromoted solid-catalyzed decomposition of oxides of nitrogen such as nitric oxide which are major pollutants of air and the environment at large. By this method, oxides of nitrogen are decomposed into molecular nitrogen and molecular oxygen by reactive passage over a solid metal oxide catalyst at an elevated temperature under irradiation at wavelengths absorbable by the catalyst. In this manner, the major oxides of nitrogen pollutants originating in the exhaust gases produced by automobile engines, jet engines used in the propulsion of aircraft, gas-turbine power generators, and the combustion of fossil fuels generally are controlled and eliminated.
