Abstract

A novel optimized monolith catalyst of CeSn_0.8W_0.6O_x/TiAl_0.2Si_0.1O_x with 12 wt% CeSn_0.8W_0.6O_x calcined at 500 °C exhibited over 90% NO removal efficiency and 100% N₂ selectivity in a broad active temperature window of 252-456 °C under GHSV less than 10,000 h^-1. Moreover, both the CO and C₃H₈ can be effectively oxidized into CO₂ over the catalyst. Comparatively a commercial V₂O₅(WO₃)/TiO₂ catalyst had no action on catalytic oxidation of CO, over which the C₃H₈ could only be oxidized to CO. Anyway, excellent redox properties and surface acidity are two active factors for the CeSn_0.8W_0.6O_x/TiAl_0.2Si_0.1O_x in catalytic removal of NO, CO and C₃H₈.
