Summary: Semiconducting heterojunction-based devices using transition metal oxides like tungsten (WO3) and titanium (TiO2) exhibit the best photocatalytic performance currently, due to the ability to optimize electron/hole injection barriers through size, morphology, and composition adjustments. However, this approach requires a deep understanding of structure-property relationships that are difficult to access through experiments.

Summary: Nanotube-structured TiO2 electrodes were formed on Ti plates by anodic oxidation in ethylene glycol solution, followed by decoration of WO3 on the nanotube surfaces electrochemically. The effects of various factors on the oxidation and product selectivity of 3-methylpyridine were investigated. It was found that decorating nanotube-structured TiO2 with WO3 significantly increased the yield of vitamin B-3 under UVA irradiation, while no products were obtained under Vis irradiation due to unselective photolytic reactions. This unexpected result was reported for the first time.

Summary: Rutile TiO2 microspheres and WO3 nanosheets were synthesized via hydrothermal treatment, and a WO3/TiO2 heterojunction was prepared with different mass ratios using physical mixing. Photocatalytic performance was evaluated using the degradation of Rhodamine B dye under simulated sunlight. The WO3/TiO2 with a mass ratio of 1:5 showed the highest photocatalytic efficiency of 91.5% within 60 minutes. Holes (h(+)) and superoxide radical (center dot O-2(-)) were found to play key roles in the degradation process. The unique type-II WO3/TiO2 heterojunction extended the light absorption range and improved photocatalytic activity.

Summary: Electrodeposited bismuth ferrite (BiFeO3) thin films were used as photoanodes for the photoelectrocatalytic degradation of methylene blue. The morphology, thickness, and optical properties of the films were characterized by XRD, FESEM, and UV-vis spectroscopy. The photoanodes showed increased band gaps and improved photocurrent response with shorter electrodeposition times. The removal of methylene blue showed higher degradation rates with shorter electrodeposition times. The electrodeposition process with citric acid improved electrode stability and reduced catalyst leaching.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
