Among various metal vanadates, cerium vanadate has been interested as selective catalytic reduction (SCR) catalyst. By incorporating SiO<sub>2</sub> and WO<sub>3</sub> into TiO<sub>2</sub> (TWS), the surface area was maximized and nanoparticle size was reduced due to Ti-O-Si bond formation. Herein, we investigate the role of WO<sub>3</sub> and SiO<sub>2</sub> in Ce-V/TiO<sub>2</sub> catalysts. More catalytic defects and oxygen species were confirmed on Ce-V/TWS surface. Increment of the V<sup>3+</sup> and V<sup>4+</sup> fraction influenced the SCR catalytic performance at wide temperature. On the basis of these results, TWS supported Ce-V exhibits the highest NH<sub>3</sub>-SCR performance at wide temperature. In addition, we confirmed that the Ce-V/TWS catalyst had enhanced stability against hydrothermal aging effects.
