Enhancing NH3-SCR Performance and Hydrothermal Stability of Ce-V/TiO2 by Introducing WO3 and SiO2 |
| 초록 |
Among various metal vanadates, cerium vanadate has been interested as selective catalytic reduction (SCR) catalyst. By incorporating SiO2 and WO3 into TiO2 (TWS), the surface area was maximized and nanoparticle size was reduced due to Ti-O-Si bond formation. Herein, we investigate the role of WO3 and SiO2 in Ce-V/TiO2 catalysts. More catalytic defects and oxygen species were confirmed on Ce-V/TWS surface. Increment of the V3+ and V4+ fraction influenced the SCR catalytic performance at wide temperature. On the basis of these results, TWS supported Ce-V exhibits the highest NH3-SCR performance at wide temperature. In addition, we confirmed that the Ce-V/TWS catalyst had enhanced stability against hydrothermal aging effects. |
