SOME ASPECTS OF THE NO REDUCTION REACTION OVER RHODIUM CATALYSTS

A theoretical study has been performed of the reduction of NO by CO ov er Rh catalysts solving the system of equations generated by applying a steady state to the adsorbed species to determine the influence of t he rates of the NO dissociation and delta-N-2 production steps on the catalyst activity (measured as CO2 production) and selectivity to N2O. As a general observation, it is concluded that joint data on activity and selectivity are required to make a critical selection of the kine tic parameters that can interpret adequately the experimental data.
