Abstract
Removal of NOx is one of the most urgent environmental issues. NO decomposition has been carried out utilizing the reductive properties of TiOx (0<x<2) (i.e., low valence materials of titanium oxides), as represented by Ti-coated Al2O3 balls prepared by fine particle bombardment, or TiOx powders (for example, so-to-speak Ti-black powders used for liquid crystal displays as the black matrix). In the absence of oxygen, NO is found to mostly decompose into NH3 by means of Ti-coated Al2O3 balls or TiOx powders at approximately 150°C, accompanied by traces of N2O. A similar result is also obtained even in the presence of about 20% oxygen. The formation of NH3 is further effective in reducing NO to give water and N2 as shown by the urea-SCR (selective catalytic reduction) system used currently in practice in diesel engines.
