چکیده (انگلیسی):

The nanocrystalline nickel oxide (NiO) particles have been successfully
prepared by a simple, fast, economical, and eco-friendly solution-combustion
method using Ni(NO3)2
6H2O (oxidizer) and sugar (dextrose as fuel). The asprepared
compound was calcined for an hour at different temperatures. The
synthesized NiO was characterized by XRD, TGA, SEM/EDX, TEM, XPS, FT-IR, and
UV–Vis spectral methods. The crystallite sizes of the NiO particles were
measured. Rietveld refinement of X-ray data matches the cubic structure with
space group of Fm3m (No. 225). The thermal behavior of as-prepared
compound was examined. Scanning electron micrographs show uniform cubic
like morphology of NiO and its chemical composition was measured. The TEM
results reveal that the particle sizes were in the order of 70–80 nm. The red
shift was noticed in UV–Vis absorption spectra. As an application part the
Zn–NiO composite coating was prepared by electrodeposition method and its
corrosion behavior was analyzed by Tafel, impedance and anodic polarization
in aggressive medium.
