Abstract

The surface part of the oxygen incorporation reaction into the model material Fe-doped SrTiO3 is investigated by in situ optical spectroscopy. Experiments close to and far from equilibrium (small and large pO2 changes) and the effect of UV irradiation on the reaction rate allow us to draw the following conclusions with respect to the kinetic processes at the surface: (i) molecular oxygen species participate in or before the rate determining step (RDS), and (ii) a single conduction band electron participates in or before the RDS of the incorporation reaction even though the bulk is p-type conducting. Probable reaction mechanisms comprising chemisorption, charge transfer, dissociation and oxygen ion transfer steps are discussed.

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.
