Ce-Ti-MoOx catalysts with different Mo contents have been prepared and used for selective catalytic reduction of NO with NH3 (NH3-SCR). As-prepared catalysts were characterized by N2 adsorption-desorption and XRD analysis. It was found that the Ce-Ti-MoOx catalyst with nominal MoO3 content of 10 % exhibited the best NH3-SCR activity, over 90 % of NO conversions could be obtained at 200 - 425 °C with GHSV of 100 000 h-1.
