Photopromoted and Thermal Decomposition of Nitric Oxide by Metal Oxides

This technical report summarizes research on decomposition of NOx by photopromoted and thermal solid-catalyzed decomposition of NO. Typical catalysts incorporated one or more metal oxides. Photopromotion of catalytic activity was observed with several catalysts. Nearly complete thermal decomposition of NO was achieved by several catalysts in the absence of O2. However, no combination of catalyst and conditions achieved satisfactory rates of decomposition of NO in the presence of target concentrations 10 percent of O2.
