High intrinsic activity of CeVO4-based catalysts for ammonia-SCR: Influence of the parameter synthesis

Résumé

Promising CeVO4 based materials for the ammonia-SCR catalysts were found as potential substitutes of conventional supported V2O5/WO3/TiO2 catalysts previously optimized for stationary sources. Indeed, the CeVO4 structure can be obtained from hydrothermal synthesis under mild conditions and then stabilized after ageing in wet atmosphere at 600°C. It was found that pH evolutions during hydrothermal synthesis can be an outstanding parameter to get optimal bulk and surface properties since strong acidic medium can be detrimental on the resulting catalytic properties.
