Abstract

A novel CeO 2 /TiO 2 -MoO 3 (Ce/TM) catalyst was synthesized by using of Mo as a bulk dopant to boost the NH 3 -SCR performance of CeO 2 /TiO 2 catalyst. It displayed 100% NO conversion at 200–350 °C under 60,000 mlg −1  h −1 and high tolerance to H 2 O and SO 2 at 250 °C. Characterization results manifested that the doping of Mo not only resulted in more Brønsted acid and Lewis acid sites formed on the Ce/TM surface, but also increased the specific surface area and redox ability of the catalyst, all of which account for the enhanced NH 3 -SCR activity.
