TiO<SUB>2</SUB>-supported noble metal catalysts, such as Pt–, Pd–, and Rh–TiO<SUB>2</SUB>, are much more active for the NO–CO reaction in the presence or absence of H<SUB>2</SUB>O, H<SUB>2</SUB>, and O<SUB>2</SUB> than the corresponding Al<SUB>2</SUB>O<SUB>3</SUB>– or other supported catalysts. They are effective even in an oxidative gas composition range for the NO–CO–(H<SUB>2</SUB>O)–H<SUB>2</SUB>–O<SUB>2</SUB> reaction, producing no NH<SUB>3</SUB> in the NO–CO–H<SUB>2</SUB>O reaction. Comparison of the catalytic activity and properties of Pt–TiO<SUB>2</SUB> with those of other supported catalysts suggests that the higher activity of the TiO<SUB>2</SUB>-supported catalysts could be attributed to their ability to activate NO molecules by the dissociative adsorption at lower temperatures.
