Abstract
In this article, low-temperature selective catalytic reduction (SCR) reaction of NO on carbon nanotube-supported vanadium (V 2O 5/CNT) catalysts was carried out. When compared with activated carbon as a support catalyst, carbon nanotubes with low load of V 2O 5 show excellent catalytic activity than that of activated carbon, and the catalytic activity of V 2O 5/CNT catalysts increases markedly in the presence of SO 2. The transient reaction experiment shows that the reaction of V 2O 5/CNT catalyst for low-temperature SCR of NO follows the mechanism of Eley–Rideal, namely by the reaction between the adsorbed NH 3 and NO in the gaseous or a weakly adsorbed state.
