Summary: A self-cleaning wood surface was achieved by applying a Bi2O3-doped silica-titanium composite film onto the wood surface using the sol-gel method. The study investigated the effects of different Bi doping amounts on the structure and photocatalytic properties of the modified wood. Bi2O3 doping inhibited crystal growth of TiO2 and the phase transition from anatase to rutile. In addition, Bi2O3 improved the photocatalytic activity of the composite film by reducing the grain size of TiO2 and increasing its crystallinity.

Summary: This article investigates the photocatalytic activity of BaBi4Ti4O15 doped with excess bismuth oxide (0-10 wt%) and the parametric study of photocatalysis. BaBi4Ti4O15 with excess bismuth oxide was synthesized via a solid-state route followed by calcination. The characterization of BaBi4Ti4O15 includes XRD, SEM, EDX, Raman spectroscopy, XPS, and direct optical bandgap measurement. The results show that BaBi4Ti4O15 with excess bismuth oxide has an orthorhombic perovskite structure and the concentration of oxygen vacancies is influenced by the amount of excess bismuth. The photocatalytic activity study reveals that 8 wt% excess bismuth has the highest activity. The parametric study indicates that initial concentration, intensity, and volume are correlated with the degradation rate. Real-life demonstration on indoor dye cleaning is also conducted. The effect of photocatalysis on BaBi4Ti4O15 is investigated by XRD and XPS.

Summary: An in-depth investigation was conducted to explore the relationship between the structure and morphology of beta-Bi2O3 nanostructured thin film annealed at different temperatures and its photoelectrochemical (PEC) performance. It was found that annealing caused significant changes in the nanostructure and the formation of a new non-stoichiometric phase (Bi2O2.33). Annealing at specific temperatures resulted in improved photocurrent density and enhanced PEC efficiency. These findings contribute to a better understanding and improvement of the PEC performance of beta-Bi2O3.

Summary: Combining morphology modification with heterojunction is an effective approach to enhance the photocatalytic activity of TiO2-based photocatalysts for wastewater treatment. In this study, a novel flower-like TiO2/Bi2O3 (FTB) photocatalyst was developed by depositing Bi2O3 nanoparticles on the surface of flower-like TiO2 (FT). The successful formation of p-n heterojunction between flower-like TiO2 and Bi2O3 was confirmed, which facilitates efficient charge separation. Due to the narrow bandgap of Bi2O3 and the unique flower-like microstructure, FTB exhibits a photocurrent 1.67 times higher than that of FT, resulting in a higher photo-degradation rate (92.7%) of levofloxacin compared to FT photocatalyst (approximately 80%). Moreover, FTB demonstrates excellent anti-interference capability towards environmental factors and good cyclability. This work provides new insights into the development of TiO2-based photocatalysts with advanced performance for antibiotic removal.

Summary: In this study, amorphous-nanocrystalline NiCr0.25Mox (x = 0, 0.02, 0.05, 0.1, 0.2, 0.4) alloy coatings for marine engineering equipment were developed via direct current magnetron sputtering. The relationship between the coating structure and performance, including composition, microstructure, corrosion resistance, and mechanical properties, was discussed in detail. The addition of Cr and Mo facilitated the formation of a dense passive film, alleviating grain boundary corrosion. The nanohardness and adhesion strength initially increased with Mo content but declined due to the formation of an amorphous phase. Notably, the NiCr0.25Mo0.1 coating exhibited superior corrosion resistance and mechanical behavior, attributed to the formation of a dense passivation film composed of Cr2O3 and Cr(OH)(3), which promoted homogeneous plastic deformation and inhibited crack propagation.
