Better Than

The NO conversion of the CeLa0.5Fe0.2/Ti is obviously better than that of the commercial vanadium-based catalyst with regard to arsenic resistance and it has good N2 selectivity, and good SO2 resistance.

Calcined Temperature

The calcined temperature of the carrier obviously affected SCR activity of catalysts, WO3/Ce0.68Zr0.32O2-500 showed the best low-temperature NH3-SCR activity due to its more Lewis acid sites and stronger redox property.

Reduction Of Nox

The redox cycle (Ce4+ + Fe2+ ↔ Ce3+ + Fe3+) over the Fe–Ce–Ti catalyst contributes to the activation of NOx and NH3 and thus the formation of reaction intermediates, leading to the high catalytic performance for the NH3-SCR of NOx.
