In this investigation, we report facile synthesis of transition metal oxide (CeO2) And (NiO) as nano oxid. The process contained two steps: first preparation of complex [(phen)2(OH2)Ni(μ SCN)Ce(μSCN)(SCN)4Ni(OH2)(phen)2] NO3(1) where phen=1,10-phenanthroline and SCN= thiocyanate. Then the precursors were complex (1) synthesized using a mix of ethanolic solution of Ni(NO3)2(2mmol), and phenanthroline(4mmol) and Ce(NO3)3(1mmol) , SCN(6 mmol). Then desired product was collected by suction filtration and characterized using Fourier transform infrared (FT-IR), Ulcalcination. In first step, tra Violet-Visible (UV-vis) spectroscopy and cyclic voltammetry (CV) method for electrochemical studies. The next step to prepare nano oxid, amount of compound (1) was placed in a furnace with a temperature of 700. After calcination of title compound, this sample studied using XRD (X-ray Diffraction)and SEM (Scanning Electron Microscopy) techniques. Particle size for several diffraction and average crystallite size were measured from the XRD data based on Debye- Scherrer¼equation. The X-ray diffraction patterns at room temperature revealed that, highly pure and crystallized Ni-Ce nano oxid as form(CeO2) And (NiO) ula with Hexagonal phases in 700°C, with an average particle size of about less than 100nm for both nano-oxide. SEM figure show that the particles have same morphology with a uniform porous surface[1].
