Summary: In this study, a hierarchical core-shell structured photocatalyst consisting of 2D ZnIn2S4 nanosheets and 1D CoS1.097 nanothorns was constructed for efficient visible light-driven hydrogen production. The optimized 8.5-CoS1.097@ZIS photocatalyst exhibited outstanding activity with a hydrogen production rate of 2632.33 mu mol g- 1h- 1 (6.42 times higher than ZIS alone) and good stability for photocatalytic water splitting. The improved performance can be attributed to the unique structure and composition of CoS1.097@ZIS, which facilitates charge separation and transfer, and inhibits charge recombination.

Summary: In this study, Ag nanoparticles decorated AgBr/BiVO4 shell/core heterojunction was synthesized and exhibited high photocatalytic activity in removing contaminants under visible-light irradiation. The enhanced photocatalytic performance can be attributed to the spatial separation of photogenerated carriers and inhibition of bulk recombination by AgBr/BiVO4 shell/core heterojunction. The localized surface plasmon resonance effect of Ag particles also improved the light absorption ability of the photocatalyst.

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: To solve the problems of electron-hole pair recombination, low solar energy utilization efficiency, and catalyst reuse, a core-shell alpha-Fe2O3/Bi2MoO6@304SS heterojunction photocatalytic was synthesized and immobilized on a 304 stainless steel wire mesh. The resulting catalyst showed high adsorption and visible-light photocatalytic activity towards ciprofloxacin (CIP), with degradation efficiencies of 96% and 92% under visible light from a 40 W LED lamp and direct sunlight, respectively. The photocatalytic mesh exhibited good structure stability and cycling performance, with the built-in electric field generated by the heterojunction significantly improving the photocatalytic activity.

Summary: This study explores the use of Cu2+ ions and CuO as co-catalysts to enhance the efficiency of WO3 in the visible light-driven photocatalytic oxidation of arsenite. The addition of Cu2+ was found to effectively suppress the dissolution of WO3, while the efficiency of CuO was slightly lower. The results show that significant improvement in the efficiency of photocatalytic oxidation of As(III) with WO3 can be achieved by adding Cu2+ ions and CuO.

Summary: Novel tungsten-modified mixed-valence tin oxides (Sn3O4) were successfully prepared by the solvothermal method using tin (II) chloride dihydrate and sodium tungstate (IV) dihydrate as precursors, with cetyltrimethylammonium bromide (CTAB) as the assistant. The presence of tungsten and the optimized amount of CTAB in the preparation method enhanced the photocatalytic dye degradation reaction, achieving almost complete decolorization of methyl orange within 40 minutes. The improved photocatalytic activity of the W-Sn3O4 catalyst was attributed to increased reduction power, enhanced separation of electron-hole pairs, extended visible light absorption range, and optimized band structure by CTAB additive.

Summary: Biodiesel, as a sustainable energy alternative, can be produced by synthesizing glycerol, which is a byproduct of biodiesel synthesis. In this study, the photocatalytic biohydrogen generation using ZnO with the aid of simultaneous deposition of copper from an aqueous biomass-derivative glycerol solution was investigated. The concentration of glycerol solution, Cu ion concentration, and reaction temperature were found to affect the biohydrogen production rate. Furthermore, the photocatalytic H2 production efficiency with ZnO could be improved by simultaneous Cu deposition.
