Synthesis and Characterization of Nanoparticles of Magnesium-Copper Oxide with Paramagnetic Properties

In the article, first a trinuclear complex under formula [Mn(phen)2(H2O) (μ-NCS)Cu (NCS)4(μ-NCS)Mn (phen)2(H2O)] that (phen= 1,10- phenanthroline) has been synthesized. This complex characterized by FT-IR, UV-Vis spectroscopirs. The electrochemical behavior of the complex was investigated by cyclic voltammeteric method. Crystal of complex was placed in the furnace at 950°C for 5h to become oxide particle of CuMn2O4. Nano oxide particle was carried out using FT-IR, X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX). Magnetic behavior of nanoparticle characterized using VSM. SEM images show that the particles have same morphology with less than 100 nm size. XRD show nanoparticles have single phase with cubic symmetry. The particle size of about 18 nm is formed. SEM images showed that the morphology of the particles obtained are almost identical with globular form.
