Summary: Binary and ternary nanocomposites of Bi2O3/CuS/Ag were successfully prepared and characterized for their structural, compositional, morphological, optical, and photocatalytic properties. The results showed that the ternary Bi2O3/CuS/Ag nanocomposites exhibited the highest photocatalytic activity in acidic medium and the best degradation performance. The improved photocatalytic efficiencies were attributed to the refinement in absorbance, obtained band gap in the visible region, and formation of heterojunctions.

Summary: Fluorescent nanohybrids based on pi-extended hydroxyoxophosphole ligands grafted onto ZnO nanoparticles are designed and studied for potential use in OLEDs as solution-processed emissive layers. The restriction of intramolecular motions of the organic fluorophore leads to highly emissive materials due to aggregation induced emission effect. Theoretical calculations and XPS analyses were conducted to analyze the interactions between organic and inorganic components.

Summary: This study presents the preparation and characterization of nanocomposites of graphene flakes (GF) combined with CuS, Fe3O4, and CuS-Fe3O4. The adsorption and photocatalytic properties of the nanocomposites were evaluated using Rhodamine B (RhB) as the model contaminant. The results showed successful attachment of CuS and/or Fe3O4 nanoparticles onto GF. The GF@CuS-Fe3O4 nanocomposite exhibited the highest RhB adsorption efficiency and photocatalytic activity, completely eliminating the dissolved RhB after 60 minutes of irradiation.
