Abstract

A macroscopic model to describe the spatio-temporal patterns observed in the CO + O2 reaction on Pt(110) is presented. We consider mass transport in the adsorbed layer as a response to the gradient in chemical potential of adsorbed CO and explicitly take into account the coupling between diffusion and the adsorbate-induced structural transformation of the substrate. Numerical integration of the model equations in two-dimensions revealed target patterns, spiral waves as well as subharmonic standing-wave patterns that closely resemble those observed in experiments. Our results also show that synchronization of the surface can be achieved through nucleation and growth processes even in the absence of gas-phase coupling.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
