Nanocrystalline TiO2 composite thin ZnO/TiO2, Fe2O3/ZnO/TiO2 and Fe2O3/TiO2 films were developed on titanium substrates by applying dip-coating technique formed by the sol–gel method. Scanning electron microscopy (SEM) evaluated the surface characteristics of the films. Results on their structure and crystallinity were obtained by means of X-ray diffraction. The samples were also characterized by X-ray energy dispersive spectrometer (EDS) and ultraviolet-visible diffuse reflectance spectroscopy. The photocatalytic activity of these films towards photodegradation of pentachlorophenol pollutant was examined and their efficiency was compared to those of the different TiO2films. It has been shown that the film photocatalysts can efficiently decompose the pollutant. The photoelectrocatalytic degradation of PCP showed important variation that decreases in the order: ZnO/TiO2 > TiO2 > Fe2O3/ZnO/TiO2 > Fe2O3/TiO2. The results showed that Zn2+ doped could improve PEC activity of titania film electrode while Fe3+ doped can not improve that of titania film electrode.

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.
