Controllable Preparation of Cu2O Microcrystals and Their Visible-light Photocatalytic Activity Toward Degradation of Methylene Blue†

doi:10.7503/cjcu20150091

Abstract

Abstract:

Cuprous oxide microcubes were prepared by solvothermal method in glycol and water medium using copper acetate as copper source, citrate as a shape directing agent. The samples were characterized by X-ray powder diffraction(XRD), X-ray photoelectron spectroscopy(XPS), scanning electron microscopy(SEM), transmission electron microscopy(TEM) and UV-Vis diffuse reflectance spectroscopy(UV-Vis DRS). The results indicate that uniform cubic Cu₂O microcrystals with the size of 0.6—1.5 μm were synthesized at 180 ℃ for 5 h by controlling the molar ratio of sodium citrate to copper acetate. The visible-driven photocatalytic activity of Cu₂O microcrystals toward the degradation of methylene blue(MB) was investigated. The results show that after 100 min visible light irradiation, the degradation rate of methylene blue with initial concentration of 30 mg/L reached 98% by using 0.3 g/L Cu₂O microcrystals in the presence of H₂O₂. The decomposition rate of MB was still above 96% even after 8 recycling uses, thus Cu₂O microcrystals show high catalytic activity and excellent stability. The photocatalytic mechanism was discussed based on the active species during photocatlytic process.
