Green synthesis and characterization of copper nanoparticles on the CuS/MCM-41

The present study reports the plant mediated synthesis of copper nanoparticles (Cu NPs) on MCM-41 and CuS-MCM-41mesoporous material. The CuS-MCM-41 sample was synthesied by solvothermal method in ethylene glycol phase. The Cu/MCM-41 and Cu/CuS-MCM-41 nanocomposites were prepared by reduction of Cu2+ ions using the plant leaf extract of Bourrache. Nanocomposites were characterized by UV-Vis spectroscopy, X-ray diffraction (XRD), Fourier transfer infrared (FTIR), and Transmission electron microscopy (TEM). The X-ray results showed the presences of pure covellite phase of copper sulfide with high crystality in MCM-41.The DRS result confirmed the presence of surface plasmon resonance (SPR) of Cu NPs in the MCM-41 and CuS-MCM-41. The Cu/CuS-MCM-41 nanocomposite will use for degradation of methylene blue (MB) under visible light.
