Interpretation of the experimental data on the reduction reaction of NO by CO on rhodium by Monte Carlo simulations and by solving the kinetic equations of the reaction mechanism

Article Abstract:

Mechanisms of the reduction reaction of NO by CO on rhodium are analyzed and discussed, solving the kinetics equations and using Monte Carlo simulations in terms of its ability to interpret the recent experiments of Zaera et al who used a molecular beam method to study experimentally the kinetics of the reaction. Uniform catalytic surfaces and the statistical incipient percolation cluster (IPC) fractal are considered in the simulations.

Dynamic Monte Carlo simulation of the NO + CO reaction on Rh(111)

Article Abstract:

Dynamic Monte Carlo simulations are used to investigate the kinetics of the catalytic reduction of NO on Rh(111) surfaces. The reaction scheme where the production of [N.sub.2] is assumed to result mainly from a pathway involving the formation of a [(N-NO).sup.*] intermediate is supported by the study and defines a reliable model capable for predicting the changes in reaction rate as a function of temperature and NO:CO gas composition.

Interaction between NO and C2H2 on Rh-Loaded CeOx (111)

Article Abstract:

C2H4 serve as a partner in the catalytic reduction of NO over Rh/CeOx, in a detailed understanding of the mechanism, CeOx serves as the reductant for the decomposition of NO. CxNy intermediates are formed on the Rh/CeOx species are more stable than C or N on Rh/CeO2 and therefore a higher temperature is required to keep the Rh/CeOx clean and active.
