FeVO 4 nanorods supported TiO 2 as a superior catalyst for NH 3 –SCR reaction in a broad temperature range

In this work, a catalyst with FeVO4 nanorods supported on TiO2 was prepared and applied for NH3–SCR reaction. A significantly enhanced low temperature catalytic activity has been achieved in the presence of 10% H2O with the active window shifting by 15°C to lower temperatures, compared to the classical catalyst with FeVO4 nanoparticles supported TiO2. For the catalyst containing FeVO4 nanorods, enhanced redox ability and enriched surface active oxygen species originated from its unique crystal structure and predominantly exposed reactive crystal facets (−2 1 0) on the catalyst surface are responsible for its improved low temperature catalytic activity.
