摘要

Cuprous oxide(Cu_2O) microcrystals were successfully synthesized via hydrothermal method using CuSO_4·5H_2O and Na_2SO_3 in HAc-NaAc buffer solution. The products were characterized by X-rays diffraction (XRD), scan election microscopy (SEM) and ultraviolet-visible (UV-vis) spectroscopy. The photocatalytic activity of the as-prepared Cu_2O powders was evaluated by the photocatalytic degradation of methyl orange solution under visible light irradiation at room temperature in air. The effects of chlorine ion on the photocatalytic activity of the Cu_2O powders were investigated and discussed. The results show that chlorine ion in solution can obviously decrease the photocatalytic activity of Cu_2O. When the concentration of chlorine ion increased to 0.5 mol/L (about Cl-concentration in the seawater), the photocatalytic ratio of Cu_2O decrease to 45% compared with the value in pure water. Increasing solution pH can enhance the photocatalytic activity of Cu_2O. The mechanism of photo-degradation was discussed.
