Summary: The use of TiO2 nanoparticles for photocatalysis for the degradation of organic dyes under UV light for wastewater treatment has been widely studied. However, the photocatalytic characteristics of TiO2 nanoparticles are inadequate. In this study, three types of nanoparticles (TiO2, ZrO2, and mixed-phase TiO2-ZrO2) were synthesized and their properties were examined. The results showed that the mixed-phase TiO2-ZrO2 nanoparticles exhibited higher photocatalytic activity for the degradation of Eosin Yellow under visible light compared to TiO2 and ZrO2 nanoparticles.

Summary: This work developed TiO2-loaded lignin-derived carbon nanofibers (TiO2@LCNFs) using electrospinning, per-oxidation, and carbonization. The study systematically investigated the effects of TiO2 content, carbonization temperature, initial RhB concentration, and solution pH value on photocatalytic efficiency. Under optimized conditions, TiO2@LCNFs achieved up to 86% photocatalytic efficiency and excellent cycling stability for rhodamine B. The superior catalytic property of TiO2@LCNFs is attributed to the synergistic effect of uniform TiO2 distribution on fiber surface and good electrical conductivity of LCNFs.

Summary: Photocatalytic technology is a promising alternative for water treatments, but its practical application is limited by low efficiency and selectivity. In this study, two-dimensional zinc oxide nanosheets decorated with copper-palladium bimetallic nanoparticles were synthesized for the degradation of organic dyes in water. The prepared composites showed superior photocatalytic performance compared to pristine ZnO nanosheets under visible-light irradiation, attributed to enhanced separation and transfer efficiency of charge carriers. The highest catalytic efficiency was achieved by CuPd/ZnO nanocomposite with 0.5 wt% CuPd, achieving 95.3% removal of methyl orange within 45 minutes. This study provides a new avenue for the design and fabrication of high-performance photocatalysts for water treatments.

Summary: To increase the capacitance of an inorganic electrode material, CoFe-layered double hydroxide (LDH) was grafted onto the surface of hexagonal-flower-like NiCo2O4. Various composites with different Co/Fe ratios were grown directly on Ni foam using the hydrothermal method. The composite with a Co/Fe molar ratio of 1:2 (NiCo2O4 @Co1Fe2-LDH) exhibited the best electrochemical performance, with a specific capacitance of 2595 F g-1 at a current density of 1 A g-1. The composite prevented aggregation of CoFe-LDH, leading to high specific capacitance and good stability.

Summary: Graphitic carbon nitride (g-C3N4), a metal-free polymer semiconductor, has attracted significant attention as a promising photocatalytic material for environmental remediation. However, g-C3N4 faces challenges such as low specific surface area, limited visible-light utilization, and high charge recombination rate. To address these issues, researchers have explored the formation of heterojunctions between g-C3N4 and metal oxides. Zinc oxide (ZnO) has been widely studied as a suitable semiconductor photocatalyst to form heterojunctions with g-C3N4 due to its unique properties and simple synthetic procedure. The synergistic effect of g-C3N4/ZnO heterojunctions enhances the photocatalytic activity through improved adsorption and photogenerated charge separation. This review summarizes the strategies for fabricating g-C3N4/ZnO-based heterojunction photocatalytic systems and highlights the photocatalytic mechanism and charge-transfer pathways of these heterojunctions.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
