WebMicrokinetic models, and there prominently KMC simulations, are generally the approach used to capture the statistical interplay between elementary processes whenever the mesoscopic property or functionality to be described is outside of thermodynamic equilibrium. Besides catalysis, notable such application areas with a similar focus on ... WebKinetic models with multiple site types (and other mathematically similar structures) have been rigorously formulated and explored in the work of Kreuzer and various co-workers.34These models are generally built by treating the adlayer as an interacting, spatially-resolved lattice gas that is then inserted into the grand canonical partition …
WebMicrokinetic models, combined with experimentally measured reaction rates and orders, play a key role in elucidating detailed reaction mechanisms in heterogeneous catalysis and have typically been solved as systems of ordinary differential equations. In this work, we demonstrate a new approach to fitting those models to experimental data. WebMicrokinetic models, combined with experimentally measured reaction rates and orders, play a key role in elucidating detailed reaction mechanisms in heterogeneous catalysis and have typically been solved as systems of ordinary differential equations (ODEs) or differential algebraic equations (DAEs).
