Abstract
This study investigated the effect of adding vanadium (V) to natural manganese oxide (NMO) in ammonia (NH(3)) selective catalytic reduction (SCR). The addition of V to NMO decreased the catalytic activity at low temperatures by blocking the active site. However, the enhancement of catalytic activity was achieved by controlling NH(3) oxidation at high temperatures. From the NH(3) temperature programmed desorption and oxygen on/off test, it was confirmed that the amount of Lewis acid site and active lattice oxygen of the catalyst affects the catalytic performance at low temperature.
