Abstract :

In the present study, NiO–NPs have been synthesized via the green method and using Eucalyptus leaf extract as a reducing and limiting agent. The morphology and structure of the NiO–NPs have been investigated via FE-SEM, FTIR, XRD, and EDX/ MAP. The results of the achieved XRD and FT-IR analyses have confirmed the formation of pure and crystalline NiO–NPs. The results showed that NiO nanostructures with smaller crystal sizes are formed using lower calcination temperatures.
