In this study, CuO microspheres were synthesized by a facile hydrothermal method. X-ray diffraction pattern indicated that the as-prepared CuO sample is presented in monoclinic phase and field emission scanning electron microscope images demonstrated that CuO were composed of CuO nanoplatelets. The catalytic activity of CuO microspheres in the degradation of methylene blue (MB) with H2O2 was investigated. It was found that the degradation ratio of MB was less than 7% in the absence of CuO catalyst, while the degradation ratio can reach about 88% in the presence of CuO catalysts. It was revealed that the degradation efficiency of MB was the highest when the dose of CuO catalysts was 20 mg.
