Abstract :

In this paper, CuO nanoparticles are synthesized using Tilia platyphyllos extract as reducing and stabilizing agents and TiO2are prepared via facile sol-gel method as an ideal support. FT-IR spectroscopy, UV-Vis spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectroscopy (EDS), and Transmission Electron Microscopy (TEM) were used to characterize TiO2, CuONPs, and CuO/ TiO2 nanocomposite. The catalytic activity of the CuO/ TiO2 nanocomposite was investigated for the reduction of Methyl Orange (MO), and Methylene Blue (MB) at room temperature. CuO/ TiO2 nanocomposite can was found to be a highly active catalyst. In addition, it was found that CuO/ TiO2 nanocomposite can berecovered and reused several times without significant loss for its catalytic activity.
