In this study, a series of WO3-m%/TiO2 samples were successfully prepared via a simple and effective sol-gel method, which were subsequently used for the NO reduction by NH3 in the temperature range of 350-600 degrees C. Structural, morphological, and BET analysis revealed that the WO3 species were dispersed evenly into titania matrix so that the samples only exhibited anatase phase with high surface area. SCR results proved that the WO3/TiO2 catalysts exhibited good catalytic properties for the NO reduction at high temperatures. The correlated relationship between compositions, temperatures and structures for WO3/TiO2 catalytic mechanism was also discussed. (C) 2011 Elsevier B.V. All rights reserved.
