Dy2O3/CuO nanocomposites: microwave assisted synthesis and investigated photocatalytic properties

Dy2O3/CuO nanocomposites were synthesized by rapid and fast microwave method in polyol solvent. Effect of time and power of microwave irradiation and type of solvent on size and morphology were investigated. Synthesized Dy2O3/CuO is characterized with X-ray diffraction (XRD) analysis, Transmission Electron Microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy, Scanning Electron Microscopy (SEM) and UV–Visible absorption spectroscopy. Photocatalytic properties for two color, methylene blue and rhodamin b under ultraviolet light irradiation were done and 54 and 47.7% degradation for MB and RB respectively.
