Summary: A magnetically separable Z-scheme FeSiB metallic glass/g-C3N4 photocatalyst with high efficiency in degrading hazardous pollutants in wastewater under universal pH conditions was prepared. The heterojunction structure formed between g-C3N4 and FeSiB MG led to improved separation efficiency of electron-hole pairs, enhancing the photocatalytic activity. The recyclability of the catalyst due to high saturation magnetization makes it convenient for practical applications.

Summary: This research investigates the development of recyclable H2O2-producing photocatalysts for in situ Fenton-like organic pollutant degradation. The results show that NiFe2O4 and CuWO4 composites have staggered valence band and conduction band positions, with NiFe2O4 acting as the reduction component. Oxygen molecules in an aqueous medium have an affinity for the NiFe2O4 surface. The study demonstrates the successful formation of H2O2 under visible light irradiation and its degradation of tetracycline using an in situ Fenton-like reaction.

Summary: We described the synthesis of a zinc oxide coated magnetite nanocomposite and its photocatalytic application for degrading methyl orange dye. The nanocomposite exhibited high photocatalytic activity, achieving 84% degradation of the dye in 120 minutes under UV light. The electron transfer mechanism between zinc oxide and magnetite was proposed to explain the degradation process. The nanocomposite also demonstrated good stability and reusability.

Summary: This study developed magnetically separable CeO2/CoFe2O4 heterojunction photocatalysts for dye degradation to reduce water pollution. The 20%CeO2/CoFe2O4 photocatalyst exhibited the highest photocatalytic performance for methylene blue (MB) degradation, with an efficiency of 88.7%. It also had a good magnetic response and could be easily separated from the dye solution. The formation of heterojunction at the interfaces of CeO2/CoFe2O4 facilitated the photogenerated charge separation and increased availability of active species, improving the photocatalytic activity.

Summary: Innovation of photocatalysts with acceptable performance and easy recyclability through magnetic separation is a crucial challenge for researchers, as these materials have the potential to improve environmental health. Fe2O3 nanostructures were effectively loaded onto ZnS/ZnIn2S4 nanocomposites via a glycothermal process. The study investigated the impact of the amount of Fe2O3 nanostructures on the structural, physical, magnetic, and photocatalytic properties of the resulting nanocomposites. The magnetic recyclable photocatalysts exhibited a flower-shaped microstructure assembled from nanosheets. The ZnS/ZnIn2S4/Fe2O3 nanocomposites showed higher saturation magnetization than the binary ZnS/ZnIn2S4 nanocomposites. Photocatalytic decolorization experiments demonstrated high removal efficiencies for Rhodamine B and Methyl orange solutions using the ZnS/ZnIn2S4/Fe2O3 nanocomposites. Additionally, the nanocomposites could be easily separated and recycled multiple times with a degradation efficiency of 60.83%. The magnetic ZnS/ZnIn2S4/Fe2O3 nanocomposites are suitable for large-scale applications in industrial water treatment systems.

Summary: The study investigated the electromagnetic polyaniline-nanocomposites materials using calcined and polydopamine functionalized nickel-zinc ferrite nanoparticles to adjust the magnetic and electrical properties, demonstrating that dopamine-coated nanoferrites nanocomposites exhibit the best electrical and electrochemical properties. The increase in DC conductivity with temperature in polyaniline nickel zinc ferrite nanocomposites indicates their semiconducting features, which can be controlled by tuning the properties of reinforcing nanoparticles through calcination and dopamine coating.
