Substituent effects on the electrocatalytic reduction of oxygen on quinone-modified glassy carbon electrodes
Literature Information

The reduction of oxygen catalysed by two sulfur-containing derivatives of anthraquinone has been investigated. The quinones were chemically grafted to a glassy carbon electrode surface and the oxygen reduction reaction in alkaline solution followed a two-electron pathway yielding hydrogen peroxide. The mechanism proposed corresponds to an electrochemical–chemical (EC) reaction where the semiquinone radical anion electrochemically formed reacts chemically with oxygen. The influence on reactivity of electron withdrawing groups present in the quinone molecules has been studied and it is shown that there is an unexpected small dependence between reactivity and standard potential of the grafted quinones. It is shown that steric effects appear important in determining their electrocatalytic properties.

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.
