Abstract
For the manufacture of metal oxide, a green technique has been combined with
nanotechnology. The manufacturing of cobalt nickel copper oxide nanoparticles was made
simple and environmentally friendly in this work. Aloe barbadensis miller, Zingiber officinale,
and Azadirachta indica leaf extracts were used to make the compounds. UV-Visible (UV-Vis)
spectroscopy, Scanning Electron Microscopy (SEM), and X-ray diffraction were used to
analyze the produced nanoparticles (XRD). To assure surface plasmon resonance of produced
nanoparticles, UV-Vis spectroscopy was employed. Scanning Electron Microscopy was used
to examine the surface morphology of green produced particles (SEM). X-ray diffraction
(XRD) examination was used to determine the crystallite size of the produced material. The
UV–Vis’s absorbance of inks was maximum at zero time and gradually decreased with the
addition of manufactured Cobalt Nickel Copper Oxide Nanoparticles. With the addition of
CoNiCuOx NPs at 5-minute intervals, this tendency becomes much more prominent. With the
addition of produced CoNiCuOx NPs, the ink absorbance is maximum and then decreases.
With the addition of CoNiCuOx NPs at 5-minute intervals, this tendency becomes much more
pronounced. The synthesized NPs have been utilized to effectively degrade inks in an aqueous
media.

Keywords: inks; nanoparticle; Azadirachta indica leaf.
