Abstract

The photocatalytic oxidation activity and photoinduced hydrophilicity of brookite-rich TiO2 film were compared to those of anatase TiO2 film under ultraviolet (UV) light irradiation. The photocatalytic oxidation activities were evaluated by the initial photodegradation rates of methylene blue and cis-9-octadecenoic acid. The rates for the methylene blue bleaching were nearly identical (−2.2 × 10−3 Abs min−1) for the brookite-rich and anatase films, and the rate for cis-9-octadecenoic acid decomposition on the brookite-rich film was slightly less than that on the anatase one (−0.08 ± 0.01 μg cm−2 min−1 and −0.10 ± 0.01 μg cm−2 min−1, respectively). However, the rate constants for photoinduced hydrophilicity, which were evaluated by the changes in water contact angles (θ) under rather weak UV light irradiation (5 μW cm−2), were better for the brookite surface than the anatase one. Moreover, the brookite-rich film became more hydrophilic (θ = 10°) than the anatase one (θ = 18°) after long time exposure to weak UV light irradiation, and showed a good ability for the photoinduced hydrophilicity.

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.
