approach with the use of three distinct alkaline activators, namely sodium hydroxide (NaOH),
potassium hydroxide (KOH), and ammonium hydroxide (NH 3 OH) and as well as extract of
Moringa oleifera leaves. The physiochemical and optical characteristics of sonochemically
synthesized nanoparticles were examined comparatively with green synthesized NiO NPs.
The comparison rendered the high-yield production of NiO nanoparticles achieved in the …
