ABSTRACT:The decomposition of absorbed NO on a Pt(100) surface is studied by using a dynamic Monte Carlo method on a square lattice at low pressure conditions. The N 2 temperature-programmed desorption spectra were simulated considering the presence or absence of lateral interactions. Moreover, the effect on NO dissociation rate, the limiting step in the whole reaction, is inhibited by coadsorbed NO, N, and O molecules. The dissociation rate for NO and N 2 desorption are enhanced by the presence of adsorbed atoms as nearest neighbors. In these simulations, values of experimental parameters, such as adsorption, desorption, and diffusion of the reactants, are included. The phenomenon is studied varying the temperature in the range of 300-550 K. Our simulations are positively compared with experimental spectra and calculated mean field models.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
