The kinetics of the reduction of NO and N2O by ammonia on a V2O5/Al2O3 catalyst (15 mass % V2O5) have been measured over the temperature range 300-480 °C at atmospheric pressure. The presence of water vapour in the reaction mixture retards the reduc

NH3, NO and CO2 were tested as adsorbates for selective determination of exposed surface area of V2O5 on a V2O5/Al2O3 catalyst. The most promising appears to be CO2 which interacts with the support Al2O3 only.
