“…We have already proposed a detailed surface reaction mechanism for the NO-CO system on Pt catalysts and found good agreement with literature experimental results on supported Pt catalysts (Mantri and Aghalayam, 2007a). An important improvement over other reaction mechanisms is that we include the N 2 O formation in an explicit set of reactions, and are able to quantitatively capture the change in selectivity from N 2 O at lower temperatures, to N 2 at higher temperatures.…”

“…However, a reliable, quantitative reaction mechanism capable of capturing experimentally observed features is not available for the NO-CO reaction. Our proposed elementary reactions mechanism for the NO-CO system on Pt and Ir catalysts mainly consists of molecular NO adsorption, dissociation of adsorbed NO to form adsorbed N and O species, formation of N 2 and N 2 O and the oxidation of molecularly adsorbed CO to form CO 2 (Mantri and Aghalayam, 2007a). Most of the activation energy values for Pt(111) are from various literature sources, while semi-empirical Unity Bond Index-Quadratic Exponential Potential (UBI-QEP) (Shustorovich and Sellers, 1998) calculations are performed to obtain the corresponding numbers for the Ir(111).…”

“…Supported catalysts are used in several industries, including automotive and petro-chemicals, for controlling chemical reactions. The catalysts are often used to meet regulatory agency requirements to reduce harmful engine emissions [1,2]. Typical supported catalysts have metal catalyst particles attached to the surface of an inert support structure.…”

“…Several groups published detailed analysis of the surface reaction steps and reaction mechanism using non-conventional techniques such as transient response method, Monte Carlo simulation, feed composition forcing periodic operation etc. [6,[12][13][14][15][16][17][18]. Generally, NO dissociation over catalytic site is considered as a key surface reaction step.…”
