Abstract
This article is focused on preparation of Ni(II), Pd(II) and Ru(III) oxides in the nanoscale form from the complexes of N,N,N,N-tetradentate Schiff base with Ni(II), Pd(II) and Ru(III). The complexes have been synthesized and characterized by elemental analyses, magnetic susceptibility, molar conductivity, 1H and 13C NMR, FT-IR, UV-Vis, mass, and TG-DTG analysis. The accumulated data indicate that the central metal ion in the complexes is coordinated with four nitrogen atoms of the imino and amino groups. The complexes are characterized by a 1 : 1 metal : ligand ratio and octahedral geometry except for Pd(II) complex which has a tetradentate structure. The complexes have been used as precursors for NiO, PdO and RuO2 preparation of NPs by thermal decomposition at 600°C in the static air. Formation of the NPs is discussed in terms of FTIR, XRD, SEM, and TEM analyses data. The rate of catalytic decoloration activity of Malachite green dye under the action of metal oxides is considered. The dye has been successfully decolorized in presence of the NPs at room temperature.
