We investigated the effects of annealing in air on fluorinated N-doped TiO2 (F/N–TiO2) photocatalysts prepared by hydrothermal process. The textural properties (specific surface areas) and surface properties (surface defect density, surface Ti–F density) were significantly modified upon annealing. In contrast, due to the shielding effect of surface fluorination, the phase transformation from anatase to rutile as well as removal of N-dopants during annealing was greatly inhibited. The evolution of the chemical nature of doped nitrogen species upon annealing in air was investigated and correlated with the generation and annihilation of oxygen deficiency. The defect density dominated the visible-light absorption and production of active ˙OH. The textural properties and the surface characteristics were crucial for UV-light photocatalytic performance, while the visible-light photocatalytic activity was mainly associated with the defect density. The 300 °C-annealed F/N–TiO2 sample showed considerable photocatalytic activity under both UV and visible-light irradiation.

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.
