Electrolysis of acidic H2O–D2O mixtures has been performed using the well established mercury drop electrode. The experiment was done in order to study, for the first time in a chemical reaction, possible quantum behaviour of hydrogen species which is evident from neutron and Raman light scattering studies. Rate constants and the Tafel slope of the examined reaction show striking deviations from the expected conventional behaviour for the nominal D and H concentrations. Limitations of the applicability of simple reversible thermodynamics and equilibrium statistical mechanics to the electrochemical process under consideration are revealed.

Physical Chemistry Chemical Physics

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.
