Summary: This study examined the use of NiSe2/Ag3PO4 nanocomposite catalysts for photocatalytic degradation of RhB and BPA pollutants. The 20% NiSe2/Ag3PO4 composite exhibited the highest photocatalytic efficiency for both pollutants. Various factors, including dye concentration, catalyst amount, pH, and reaction time, were investigated. The study found that the 20% NiSe2/Ag3PO4 catalyst effectively degraded 10 ppm RhB in 20 min and 20 ppm BPA in 30 min. SEM, PXRD, and energy-dispersive X-ray spectroscopy were used to analyze the physical properties of the samples. The combination of NiSe2 and Ag3PO4 played a crucial role in enhancing the stability of the photocatalysts. The photodegradation of both RhB and BPA followed pseudo-first-order kinetic models with specific rate constants. A Z-scheme reaction mechanism involving superoxide anion radicals and holes was proposed to explain the photodegradation process.

Summary: Access to clean water is a major challenge in the 21st century due to the growing population. This study focuses on utilizing renewable energy sources to reduce water pollutants, particularly the harmful molecule Bisphenol A (BPA) found in plastics. By synthesizing two photocatalysts (BiOI and Bi2MoO6) using a microwave-assisted route, and creating BiOI/Bi2MoO6 heterostructures, the researchers found that the flower-like shape of BiOI/Bi2MoO6 exhibited high photocatalytic activity for BPA degradation. This was attributed to their matching electronic band structures and interfacial contact, enhancing the separation of photo-generated charges.

Summary: Compared to UV-driven catalysts, the use of sunlight to design efficient visible light catalysts has been less explored. In this study, Fe3O4@ZnO@ZIF-8 three-component core-shell nanoparticles were prepared and their photocatalytic degradation performance was investigated under visible light using Rhodamine B (RhB) as a model contaminant. It was found that Fe3O4@ZnO@ZIF-8 achieved a significant enhancement in the photo-catalytic degradation efficiency with 98% of RhB degraded within 100 min, and a reaction rate constant of 0.0292 min-1. These findings highlight the importance of precise tailoring of core-shell Fe3O4@ZnO@ZIF-8 for achieving desired degradation efficiency of organic pollutants under visible light.

Summary: The unintentional leakage of dyes into the aquatic environment has caused serious water contamination globally, risking the health of aquatic life and humans. Hence, there is a strong need for adaptable and effective measures to address this environmental challenge. In this study, a visible light-induced catalyst based on the Ce0.2Co0.8Fe2O4/g-C3N4 composite was synthesized using the hydrothermal technique. The catalyst's morphological, structural, and photoluminescence properties were characterized, and its photocatalytic proficiency was evaluated by degrading rhodamine B under visible light irradiation. The Ce0.2Co0.8Fe2O4/g-C3N4 composite demonstrated superior degradation potential compared to other catalysts, attributed to interfacial migration of photo-induced charge carriers. Additionally, the catalyst showed excellent stability in successive cycles, providing a low-cost approach for visible-light responsive catalysts in environmental remediation applications.

Summary: This study synthesized noble metal-doped BiOBr microspheres using a solvothermal method and tested their degradation performance of phenol under visible light. The results showed that the Pd-doped BiOBr material exhibited enhanced degradation efficacy, about 4 times higher than pure BiOBr. This improvement was attributed to enhanced photon absorption, reduced recombination rate, and increased surface area facilitated by surface plasmon resonance. Additionally, the Pd-doped BiOBr sample showed good reusability and stability after 3 cycles of operation. A plausible charge transfer mechanism for phenol degradation over the Pd-doped BiOBr sample was also revealed. These findings highlight the potential application of noble metal-doped semiconductor metal oxides as visible light materials for the elimination of colorless toxins from untreated wastewater.

Summary: Photoelectrochemical (PEC) solar water splitting using semiconductor electrodes is a promising method for converting solar energy into hydrogen fuel. In this study, strontium titanium oxynitride (STON) with anion vacancies was prepared via solid phase synthesis and used as a photoelectrode for alkaline water oxidation. The PEC efficiency was improved by depositing a cobalt-phosphate (CoPi)-based co-catalyst on the surface of the STON electrode. The enhanced oxygen evolution kinetics and reduced surface recombination of photogenerated carriers contribute to the observed PEC enrichment. Additionally, the CoPi modification of perovskite-type oxynitrides presents a new avenue for developing efficient and stable photoanodes in solar-assisted water-splitting reactions.

The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
