| Research Abstract |
Aluminium phosphate supported platinum catalysts was physically combined with solid acidic metal oxides, e. g. zeolite. Such combined catalysts possessed good NOx purification activity by using hydrogen as a reducer. Diffuse reflectance infrared Fourier transform spectroscopy revealed that ammonia intermediate species generated during the reaction stably adsorbed at Br & oslash ; nsted acid sites of metal oxides and served as a good reducer against NOx like a NH_3-SCR reaction, resulting in high nitrogen selectivity.
