Abstract

In the present work, Orthorhombic NiS nanoparticles were obtained by simple chemical method using
thiocarbohydrazide as a sulfur source. X-ray diffraction (XRD) pattern was indicated the formation of orthorhombic structure
of NiS, energy dispersive X-ray spectrum (EDS), Fourier Transform Infra-Red Spectroscopy (FTIR) techniques, High
resolution transmission electron microscope (HRTEM), and scanning electron microscope (SEM) techniques were employed
to study the chemical composition and morphology properties of the obtained sample. Crystallite size was determined by
Debye—Scherrer formula and was found to be 15.76 nm. The EDS spectrum confirms the purity of the prepared
nanoparticles. Optical analyses were done by UV—visible. The band gap was calculated by Tauc relation and was found to
be 4.702 eV.
