Abstract
The effect of an NO isotope on the kinetics of lean-NOx catalysis in (NO+C2H4+O2) reaction mixtures over Pt-ZSM-5 was theoretically analyzed and compared with experimental data obtained with a fixed-bed plug-flow reactor. The large kinetic isotope effect, as well as kinetic oscillations observed previously, was explained by NO decomposition kinetics on Pt surfaces which undergo phase transition between (1×1) and (hex) phases induced by adsorbed reactant species. Results indicate the importance of NO decomposition kinetics in lean-NOxcatalysis, lending further support to a lean-NOxreduction mechanism which involves NO decomposition accompanied by hydrocarbon oxidation.
