A hydrothermal approach was used to prepare TiO2 nanowire then decorated with CdS-NPs. XRD, FTIR, HRTEM, FE-SEM, EDX, XPS, and optical properties were exploited to investigate their characteristics. A 0.05 M CdS/TiO2 showed high degradation efficiency toward methylene blue dye using UV-Vis light. The degradations were 95.46, 88.94, and 54.86% for CdS/TiO2, TiO2-NWs, and CdS-NPs, respectively. Different parameters that affect the degradation process were studied. Antibacterial activity of nanocomposites was carried out against pathogenic bacteria using diffusion methods. The hybrid nanocomposite CdS/TiO2 also showed larvicidal activity against Culex pipiens. 收起
