Spherical Cu₂O Assembled by Small Nanoparticles and Its High Efficiency in Photodegradations of Methylene Blue Under Different Light Sources

Abstract

Well-dispersed mesoporous spherical Cu₂O assembled by small nanoparticles was synthesized by a green and rapid solution route at room temperature under assistance of ultrasonic, using eco-friendly ascorbic acid(AA) as the main reducing agent and glucose as a weak reducing agent and soft template. The Cu₂O spheres were characterized by XRD, SEM, HRTEM, XPS and N₂ adsorption-desorption isotherm. Its optical property was studied by UV-Vis diffuse reflectance absorption spectrum and the photocatalytic activities were evaluted by photodegradations of methylene blue(MB) under different light sources. The results show that each spherical Cu₂O(ca. 200 nm in diameter) was accumulated by numerous small nanoparticles of 8―10 nm and mesopores exist between the nanoparticles, which result in a high BET surface area. The spherical Cu₂O exhibits good light-harvesting ability in both UV and visible light region and excellent photodegradation activities to high concentrations of MB solutions under both UV-visible light and visible light.
