  • Abstract
    The adsorption of reactants over the commerciallized SCR catalyst surface was investigated by EPR, as well as the influence of H2O and SO2. The results showed that the V4+ over the catalyst could be oxidized under NO + O2 atmosphere, and NH3 was adsorbed on Brönsted acid sites. The amounts of V4+ and super oxide ions were promoted at the presence of H2O and SO2 after adsorption. However, the intensity of Fe3+ decreased when H2O and SO2 were present, indicating the favorable effect of Fe3+ for anti-poisoning.
