Ultrasound assisted synthesis of {[Cu2(BDC)2(dabco)].2DMF.2H2O} nanostructures in the presence of modulator; new precursor to prepare nano copper oxides

As a new precursor to prepare nano copper oxide, nanostructures of porous metal organic framework (MOF) {[Cu2(BDC)2(dabco)].2DMF.2H2O} (1) have been synthesized in the presence of acetic acid as a modulator via sonochemical method. Different concentrations of metal ion, organic linkers, modulator reagent and also different sonication times were held to improve the quality of nanostructures. Ultrasound irradiation helps nucleation step of the oriented attachment of modulation method and nanoparticles with a few nanorods has been prepared. As prepared MOF was calcinated at 500 °C to prepare nano CuO and Cu2O. Compound 1, CuO and Cu2O nanostructures were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray powder diffraction (XRD).
