Low-Temperature Selective Catalytic Reduction of NO with NH3 over V/ZrO2 Prepared by Aerosol Technique: Structural and Catalytic Properties

A series of V/ZrO₂, V-WO_x(0.66)/ZrO₂, and V-MoO_x(0.66)/ZrO₂were synthesized by adopting one-step aerosol technique and investigated for low-temperature NH3-SCR of NO. Catalytic systems we described will be one of the most promising approaches for low-temperature SCR of NO with ammonia. We found some remarkable effects of zirconia as dopant in V₂O₅.
