Abstract

The gas-surface interaction model of the open-source gas and plasma simulation tool PICLas has been extended for the simulation of catalytic reactions. A variety of reaction mechanisms have been implemented, including multiple adsorption models, desorption, the Eley-Rideal and the Langmuir-Hinshelwood mechanism. Modeling is based upon macroscopic reaction data and parameters derived from experiments or ab-initio quantum calculations. The implementation has been validated through a comparison to analytical reaction rates. Simulations of the carbon monoxide and oxygen reaction network on a Pd(111) surface are performed and compared to experimental data obtained by temperature-programmed desorption spectra and molecular beam measurements. The results show good agreement with the measurement data.

期刊介绍： The focus of CPC is on contemporary computational methods and techniques and their implementation, the effectiveness of which will normally be evidenced by the author(s) within the context of a substantive problem in physics. Within this setting CPC publishes two types of paper. Computer Programs in Physics (CPiP) These papers describe significant computer programs to be archived in the CPC Program Library which is held in the Mendeley Data repository. The submitted software must be covered by an approved open source licence. Papers and associated computer programs that address a problem of contemporary interest in physics that cannot be solved by current software are particularly encouraged. Computational Physics Papers (CP) These are research papers in, but are not limited to, the following themes across computational physics and related disciplines. mathematical and numerical methods and algorithms; computational models including those associated with the design, control and analysis of experiments; and algebraic computation. Each will normally include software implementation and performance details. The software implementation should, ideally, be available via GitHub, Zenodo or an institutional repository.In addition, research papers on the impact of advanced computer architecture and special purpose computers on computing in the physical sciences and software topics related to, and of importance in, the physical sciences may be considered.
