Abstract
In this report, nano-powders of metal-organic frameworks (MOFs), were synthesized by mechanochemical method for one model system and its structure was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and X-ray powder diffraction (XRD). The thermal stability of synthesized compound has been studied by thermal gravimetric (TG) and differential thermal analyses (DTA). The CuO nanoparticles were obtained by thermolysis of MOF at 180°C with oleic acid as a surfactant. The obtained CuO nanoparticles were characterized by FT-IR, XRD and SEM to depict the phase and morphology. This study demonstrates that the MOF compounds may be suitable precursors for the simple one-pot preparation of nano-scale metal oxide materials with different and interesting morphologies.
