A novel Ni-Ti-O mixed-oxide catalyst was prepared by a homogeneous coprecipitation method and tested in the selective catalytic reduction of NO by propene (C3H6-SCR) in the presence of excess O2. Catalysts with different molar ratios of Ni-Ti were characterized using X-ray diffraction, N2 adsorption-desorption, pyridine adsorption, temperature-programmed desorption, and in-situ Fourier-transform infrared spectroscopy. The Ni1Ti1 catalyst showed good activity in C3H6-SCR at 430°C and the NOx conversion achieved 68%. This catalyst displayed an anatase structure and had a high surface area (149 m2/g), which is helpful to enhance the catalyst activity. Lewis acid sites were beneficial for adsorbing nitrate, which was the main intermediate produced during the SCR of NO by C3H6. © 2013, Dalian Institute of Chemical Physics, Chinese Academy of Sciences.
