Abstract

Minimal bromate oscillators represent the simplest version of the oscillatory reactions based on the chemistry of the oxybromine species. Here, we present numerical and experimental evidence of the existence of reaction–diffusion waves in the ferroin catalyzed minimal bromate oscillator. The wave dynamics depend not only on the characteristic chemical timescales but also on those of the diffusive matter exchange which occurs between the reaction–diffusion medium and its environment. We show that the extended reactivity of the ferroin catalyst towards the oxybromine species plays an essential role in the observed phenomena. For the cerium catalyzed minimal bromate oscillator the simulations support only the formation of spatial bistability.

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.
