Synthesis and characterization of nanoparticle (NiCo2O4) using precursor {[Co(phen)2]2Ni(SCN)6}.2H2O

In this investigation , we report a new nanostructured was prepared from heteronuclear complex of formula {[Co(phen)2]2Ni(SCN)6}.2H2O (1) (phen = 1,10-phenanthroline and SCN= thyocyanide ) has been prepared in aqueous solution at room temperature. This complex was purified and characterized by FT-IR , UV-vis and atomic absorption spectroscopes.The purpose of this research, synthesis of triple-core complex Co(ІІ) and Ni(ІI) with SCN and Phen as ligand. The linear thiocyanate group can be present in compounds as an anion or as a ligand a monodentate ligand coordinated to sulfur or nitrogen, or a bridging ligand. This complex characterized using FT-IR, UV-vis spectroscopy and cyclic voltammetry (CV) method for electrochemical studies. To prepare nanoparticles, amount of compound (1) was placed in a furnace with a temperature of 900. After calcination of this compound, sample studied using XRD and SEM techniques. Particle size was measured from the XRD data based on Debye- Scherrer¼equation. The X-ray diffraction patterns revealed that, highly pure and crystallized Co-Ni nanoparticles as NiCo2O4 formula with Cubic phases in 900°C, with an average particle size of about less than 100nm for both nano-oxide[1]. SEM figure show that the particles have same morphology with a uniform porous surface.
