Description
Summary:This study focuses on the preparation and characterization of single phase NiO nanoparticles. First, nickel- o-phthalate complexes as precursor were synthesized by semisolid phase reaction method and then NiO nanoparticles were obtained via a solid-state decomposition procedure of layered coordination nickle- o-phthalates formulated as [Ni(pht)(H 2O)] and [Ni(pht) 2]. Transmission electron microscopy (TEM) analysis demonstrated NiO nanoparticles with an average diameter of about 15 nm. This study focuses on the preparation and characterization of single phase NiO nanoparticles. At first, nickel- o-phthalate complexes as precursor were synthesized through semisolid phase reaction method and then NiO nanoparticles were obtained via a solid-state decomposition procedure of layered coordination nickle- o-phthalate complexes formulated as [Ni(pht)(H 2O) 2] and [Ni(pht) 2]. In addition, the effects of calcination temperature and metal-to-ligand ratio on the particle size and morphology of NiO were investigated. Thermogravimetric analysis (TGA) was applied to determine the thermal behavior of complexes. The crystalline structure of products by X-ray diffractometer (XRD), morphology of particles by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were studied. The composition of as-prepared sample was studied by X-ray photoelectron spectroscopy (XPS) spectra. Analysis of FT-IR spectra confirmed the composition of products. The magnetic property was studied with vibrating sample magnetometer (VSM).
