Abstract

Different methods have been reported for the preparation of CuO nanoparticles with different sizes and shapes in the literature. One of them that has recently been gained considerable attention because of the high pure and perfect structure products, is the pyrolysis of copper complexes containing organic ligands. So, in this work, at first, two new precursors, CuL1 and CuL2, were synthesized by the reaction of Cu(CH3COO)2. H2O with azo-azomethine derivatives, H2L1 and H2L2, and characterized with several techniques. The results indicated that the ligands are bound to the Cu(II) ion center as anionic and tetradentate with N and O donor atoms. In the next step, CuO nanoparticles were synthesized from pyrolysis of the mentioned precursors at 550 º C for 24h. The synthesized nanoparticles were characterized and studied with several techniques such as FT-IR spectroscopy, powder X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). The investigation of diffraction patterns indicated the single-phase CuO system with a monoclinic structure for nanoparticles. Also, the comparison of diffraction patterns showed that the CuO nanoparticles obtained from CuL2 have higher crystallinity. Finally, SEM images showed that the shape of CuO nanoparticles obtained from CuL1 is spherical, while the shape of CuO nanoparticles obtained from CuL2 is cubic. In addition, CuO nanoparticles obtained from CuL2 have a smaller size. These nanoparticles show a high tendency for aggregation.
