Lifetime and diffusion coefficient of active oxygen species generated in TiO2 sol solutions
Literature Information
Mitsuhide Okuda, Toru Tsuruta, Kenji Katayama
Active oxygen species generated by photoexcitation of TiO2 sol solutions were directly observed by the single-shot near-field heterodyne transient grating method. Transient responses were compared in the presence and absence of various kinds of scavengers such as sodium azide, dimethyl sulfoxide, and superoxide dismutase, and three components of the transient responses were assigned to hydroxyl radicals, hydrogen peroxide, and superoxide radicals. The diffusion coefficients of each active oxygen species were obtained by the analysis of the transient responses, and it was revealed that they were 1–3 orders smaller than those for molecules with a similar size. It was proposed that this is because the active oxygen species are under equilibrium between free radicals and adsorbed species on a TiO2 surface. Furthermore, it was suggested that the adsorption equilibrium for each species was varied depending on the pH of the solutions.

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.
