Summary: A novel ZnS/MoS2/Fe3O4 magnetic nanocomposite was synthesized and characterized. The nanocomposite showed increased photocatalytic efficiency compared to the binary one, thanks to reduced electron-hole recombination and band gap energy. It also demonstrated stable recycling performances due to its magnetic properties.

Summary: A highly efficient magnetic recyclable Z-scheme ternary Fe3O4/TiO2/g-C3N4 heterojunction photocatalyst was designed through the hydrothermal method. The prepared photocatalysts were characterized and showed superior photocatalytic degradation efficiency for organic dyes and Cr(VI) under simulated solar light irradiation. The increase in photocatalytic activity of the ternary photocatalyst was attributed to the enhancement in electron-hole pair separation and the construction of the Z-scheme heterojunction structure. The results suggest that ternary photocatalysts have potential applications in real-world wastewater treatment.

Summary: CuxO/TiO2 (x=1,2) nanocomposite photocatalyst was prepared on copper wire via chemical-thermal oxidation and the sol-gel method. The characterization analysis confirmed the presence of two types of copper oxides and TiO2, forming a multicomponent heterostructure between semiconductors. The nanocomposite exhibited nanowires nanoparticles morphology and had a band gap energy of 1.85 eV suitable for visible light photocatalysis. A three-level three-factor Box-Behnken design (BBD) based on response surface methodology (RSM) was used to optimize the photocatalytic degradation of methylene blue (MB) dye, with pH and dye concentration identified as the most important variables. The optimal operating conditions resulted in a dye degradation efficiency of around 99%. The nanocomposite showed high stability and ease of recovery due to its wire form, and the kinetics study confirmed the applicability of the Langmuir-Hinshelwood (L-H) model for dye photodegradation.

Summary: By grafting polydopamine (PDA) onto the core-shell nanocomposite Fe3O4@SiO2@TiO2 (FST), a multifunctional photocatalyst FST@PDA was prepared with high degradation rates for pollutants under visible light. The presence of strong covalent bonds between FST and PDA contributes to the good safety and high recyclability of the prepared photocatalyst.

Summary: A polypyrrole-modified Fe3O4/SiO2/TiO2 composite material was successfully synthesized on the FST surface by in situ polymerization of pyrrole. The structural, morphological and magnetic response were characterized, and the catalytic activity of the material was evaluated. The results showed that FST/PPy exhibited excellent photocatalytic activity and the degradation rate was significantly improved under visible light. Furthermore, the photocatalyst could be easily recycled using a magnet.

Summary: A nanocomposite of WO3/Fe3O4 was successfully prepared and characterized by various techniques, showing uniform distribution of Fe, W, and O atoms. The nanocomposite exhibited spherical particles and a band-gap energy of 1.2 eV, with a magnetization of 21.21 emu/g. The optimized conditions of pH 5, dose of photocatalyst 1.0 g.L-1 and amount of pollutant 20 mg.L-1 led to a 65% reduction in COD values, demonstrating efficient photodegradation of yellow water effluents. The central composite experimental design helped in determining the impact of independent variables on photodegradation efficiency.

Summary: TiO2-based materials have shown limitations in their application due to defects such as rapid recombination of photogenerated electrons and wide bandgap. In this study, a TiO2/C nanocomposite was prepared by carbonizing titanium alginate coordination compound and showed high efficiency in photocatalytic degradation of methylene blue under simulated sunlight. The study also demonstrated the feasibility of preparing photocatalysts from polysaccharide-based coordination compounds and provided a promising approach for high-efficiency photocatalyst synthesis.

Summary: This study synthesized a TAFTN nano-composite and used photo-induced ROS stress for photocatalytic bacterial inactivation. The disrupted proteins were found to be related to bacterial death during TAFTN-photocatalysis under sunlight. The toxicity analysis confirmed that the inactivated bacteria had no detrimental impact on a zebrafish model, and the TAFTN-photocatalysis showed consistent efficacy in killing bacterial cells in natural seawater.
