ABSTRACT
Nickel oxide (NiO) nanoparticles (NPs) were successfully synthesized by utilizing the waste shell
powder of Prunus dulcis (almond) through a simple, environmentally sound, cheap, and novel green
approach. The almond shell powder was used as a stabilizing and reducing agent for the synthesis
of NiO nanoparticles from NiNO3.6H2O solution at 60 ºC and pH 12. FTIR studies verified the synthesis
of NiO NPs by the appearance of a characteristic vibrational peak at 611.97cm-1 whereas an absorption
peak at 267 nm appeared in the UV-Visible spectrum. However, the XRD and SEM analyses have
shown the amorphous nature of synthesized NiO NPs. The cyclic voltammetry (CV) curve of NPs
clearly indicated the redox reaction and the reversible behavior of NiO NPs. The galvanostatic charge
discharge (GCD) curves have shown a higher charging time as compared to the discharging time.
