Abstract

Abstract The Cu@Cu ₂ O nanocomposites were synthesized by solution-phase synthesis of Cu nanoparticles in microfluidic reactor at room temperature, followed by controlling the oxidation process. The size, morphology, elemental compositions, and the chemical composition on the surface of Cu@Cu ₂ O nanocomposite were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). Experimental results demonstrated that the surface of the Cu nanoparticles was oxidized to Cu ₂ O which serves as the shell of nanoparticle. The amount of Cu ₂ O can be controlled by varying the drying temperature. Additionally the binary Cu@Cu ₂ O nanocomposite along with H ₂ O ₂ exhibited its potential as an excellent photocatalyst for degradation of methylene blue (MB) under UV irradiation.
