In this work, thermal decomposition of the [Co(NH3)5(H2O)](NO3)3 precursor complex was investigated under solid state conditions. Thermal analysis (TG/DTA) showed that the complexwas easily decomposed into the Co3O4 nanoparticles at low temperature (175 °C) without using any expensive and toxic solvent or a complicated equipment. The obtained product was(More)
The chelating properties of diethanoldithiocarbamate (DEDC) and π-electron flow from the nitrogen atom to the sulfur atom via a plane-delocalized π-orbital system (quasi ring) was studied using a density functional theory method. The molecular structure of DEDC and its complexes with Zn(II), Cd(II), and Hg(II) were also considered. First, the geometries of(More)
In this paper, Keggin-type heteropoly acids H3PMo12O40 (PMo12), H3PW12O40 (PW12) and H4SiW12O40 (SiW12) were successfully supported on silica-coated perovskite type LaMnO3 nanoparticles by a simple acid-base reaction. These novel hybrid nanomaterials (denoted as LaMnO3@SiO2/PMo12 (1), LaMnO3@SiO2/PW12 (2), and LaMnO3@SiO2/SiW12 (3)) were characterized by(More)
In this work, we have synthesized spherical silver nanoparticles (Ag NPs) by a low-cost, rapid, simple and ecofriendly approach using Date palm fruit extract as a novel natural reducing and stabilizing agent. The product was characterized by UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission(More)
Magnetic CoFe2O4@ZnS core-shell nanocomposite was successfully synthesized via one-step hydrothermal decomposition of zinc(II) diethanoldithiocarbamate complex over CoFe2O4 nanoparticles at low temperature of 200°C. The obtained nanocomposite was characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, UV-Vis spectroscopy, field emission(More)
