Summary: The study focuses on using MoS2/TiO2 nanocomposites to remove mixed dye pollutants through a two-stage adsorption/photocatalysis process. By using a high percentage of MoS2 in Stage-I and a low percentage in Stage-II, the process showed complete removal of methylene blue dye 5 times faster than conventional single-stage water treatment processes. Additionally, the method demonstrated excellent performance in removing mixed dye pollutants even at higher concentrations.

Summary: In this study, a simple chemical synthesis method was used to prepare polypyrrole/silver/graphene (Ppy/Ag/Gr) ternary nanocomposites with varying concentrations of graphene. The interaction between polypyrrole, silver, and graphene was studied using XRD, FTIR, and UV-Vis spectroscopies. The results showed that the addition of the optimum concentration of graphene into Ppy/Ag enhanced its photocatalytic property. Furthermore, it was confirmed that the enhancement of photocatalysis in the Ppy/Ag/Gr sample was due to the increased surface area.

Summary: A new strategy to synthesize carbon/TiO2 gel using the sol-gel method is proposed. The synthesized material was characterized and shown to be an effective adsorbent and visible light photocatalyst. The material's high surface area and mesoporous structure allowed for high adsorption capacity, and its modified electronic structure resulted in reduced bandgap and efficient daylight photocatalytic activity.

Summary: A novel visible-light responsive photocatalyst (Ag-BaTiO3/GO) was fabricated by depositing Ag nano-particles and GO sheets onto the surface of BaTiO3 nanorods using photodeposition and hydro-thermal methods. The ternary photocatalyst showed superior activity in degrading crystal violet dye (CV) and antibiotic ofloxacin (OFL) under visible light, with high degradation efficiency and rate constants. The enhanced photocatalytic performance was attributed to the SPR effect of Ag and the properties of GO, such as strong adsorption capacity and excellent electron mobility.

Summary: Three-dimensional (3D) Sb2X3 (X = S, Se) nanowires/graphene aerogel (Sb2X3/GA) monoliths were prepared by a hydrothermal route and exhibited excellent photocatalytic performance under visible light irradiation. The degradation efficiencies of Sb2X3/GA for dyes and antibiotic drugs were significantly higher than those of pristine Sb2X3 nanowires, thanks to the synergistic effect between Sb2X3 nanowires and graphene aerogel. These findings offer an innovative strategy for designing 3D visible-light-responsive photocatalysts for water purification.
