CuO dandelion-like microspheres were synthesized using a simple and green coprecipitation method. As-prepared CuO microspheres were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and diffuse reflectance spectroscopy (DRS). The photocatalytic activity of this nanostructure on the degradation of dye pollution of methylene blue with different concentrations between 10-50 mg/L in presence of H2O2 was investigated under 7 W LED lamp. The studyof results shows that the amount of of degradation of methylene blue is low in the absent of H2O2, and afteradding H2O2, it significantly increased. The amount of required H2O2 was studied. It was found that synthesized nanocatalyst in the presence of a very small amount of H2O2 (50 μL), has the ability to destroy 100% of methylene blue with 20 mg/L concentration.
