Preparation of nanocrystalline Cu2O and its catalytic degradation of methylene blue

摘要：

The nanocrystalline Cu2O has been successfully prepared by the solvent-thermal method using CuSO4·5H2O and NaOH as the raw materials and glucose as the reducing agent. The Cu2O prepared was characterized by X-ray diffraction(XRD) and transmission electron microscopy(TEM). The degradation of methylene blue using Cu2O as catalyst without lights and stirring was investigated, and the best catalytic condition was obtained: the amount of Cu2O, 0.400 g/L, H2O2, 2.5mL(concentration, 12.63%), the initial methylene blue concentration,10 mg/L. The rate of degradation was more than 95% after 50 min under the above condition.
