Abstract
The catalytic properties of transition metal oxides (Cr, Ce, and Co) supported on ZrO2 synthesized by various methods, as well as the effect of rhodium on the performance of the Мe х O y /ZrO2 oxide systems in NO reduction with hydrocarbons (methane, propane–butane mixture, and propene) were studied. The acidity of the surface of the catalysts was studied by IR spectroscopy and ammonia temperature-programmed desorption. The adsorption of NO, propene, and their mixture on the Rh–Сr2О3/ZrO2 and Rh–СеO2/ZrO2 catalysts at temperatures of 293–623 K was studied by IR spectroscopy. The adsorption and co-adsorption of the reactants was found to differ significantly depending on the nature of the surface. The activity of the catalysts studied in NO selective catalytic reduction with hydrocarbons is due to the presence of the acidic functional groups on their surface.
