We explore simple lattice-gas reaction models for CO-oxidation on 1D and 2D periodic arrays of surface adsorption sites with CO adsorption and desorption, dissociative O2 adsorption and recombinative desorption (at low rate), and CO + O reaction to form CO2. Adspecies interactions are neglected, and adspecies diffusion is effectively absent. The models are motivated by studies of CO-oxidation on RuO2(110) at high-pressures. Despite the lack of adspecies interactions, negligible adspecies…

Catalytic conversion in nanoporous materials: Concentration oscillations and spatial correlations due to inhibited transport and intermolecular interactions.

A generalized hydrodynamic formulation is developed to effectively describe inhibited transport accounting for the effect of strong spatial correlations induced by both reaction and intermolecular interactions, and this description of transport is incorporated into appropriate reaction-diffusion equations.

Beyond mean-field approximations for accurate and computationally efficient models of on-lattice chemical kinetics.

This work uses the so-called cluster mean-field approach to develop higher order approximations that systematically increase the accuracy of kinetic models by treating spatial correlations at a progressively higher level of detail, thereby opening the way for employing them in multiscale modeling frameworks.

Discontinuous non-equilibrium phase transition in a threshold Schloegl model for autocatalysis: Generic two-phase coexistence and metastability.

For a square lattice with N = 2, it is shown that phase coexistence occurs not at a unique value but for a finite range of particle annihilation rate (the natural control parameter), which contrasts both the Gibbs phase rule for thermodynamic systems and also previous analysis for this model.

Extended families of critical and stationary droplets for nonequilibrium phase transitions in spatially discrete bistable systems.

It is recognized that LDEs can exhibit richer behavior than RDEs, specifically propagation failure for planar interphases separating distinct phases, and it is shown that this feature, together with an orientation dependence of planar interface propagation also deriving from spatial discreteness, results in the occurrence of entire families of stationary droplets.

Progress in Accurate Chemical Kinetic Modeling, Simulations, and Parameter Estimation for Heterogeneous Catalysis

Current trends and future areas of advancement in chemical kinetic modeling, simulation, and parameter estimation are described: ranging from elementary step calculations to multiscale modeling to the role of advanced statistical methods for incorporating uncertainties in predictions.

Local-metrics error-based Shepard interpolation as surrogate for highly non-linear material models in high dimensions.

A novel version of the modified Shepard interpolation method is presented which can overcome the curse of dimensionality for such functions to give faithful reconstructions even from very modest numbers of function evaluations.

A practical approach to the sensitivity analysis for kinetic Monte Carlo simulation of heterogeneous catalysis.

This study presents an efficient and robust three-stage approach that is capable of reliably evaluating the sensitivity measures for stiff microkinetic models as it is demonstrated using the CO oxidation on RuO2(110) as a prototypical reaction.
