Abstract
Nickel oxide nanoparticles were synthesized from NiCl2.6H2O
solution using aqueous extract of SyzygiumCumini at 600C and
formation of nanoparticles carried out with precipitation method, which were
centrifuged, washed, and dried. It was characterized by microscopic and
spectroscopic techniques, UV-visible spectroscopy, Fourier transform infrared
spectroscopy, scanning electron microscope, X-ray diffraction and
electrochemical impedance spectroscopy. The UV-visible spectra showed nickel
nanoparticles maximum peak at 286nm, with the reported range for nickel oxide
nanoparticles as 265-297nm. The FTIR spectra showed bands corresponding to
ethers, phenols and polyphenols which stabilized and cap the NiO nanoparticles.
The scanning electron microscope image of synthesized NiO nanoparticles showed
the nanoparticles are dense irregular structure and shapeless on the surface.
The XRD showed patterns characteristics of NiO nanomaterial. The replication
can be indexed to face-centered cubic phase NiO. The average crystallite size
is about15.5nm. The cyclic voltametry showed the modified electrode as being
electroactive.
