Green synthesis of NiO and NiO@graphene oxide nanomaterials using <i>Elettaria cardamomum</i> leaves: Structural and electrochemical studies.

ABSTRACT: An eco-friendly synthetic route was developed for the formation of nickel oxide (NiO_aq and NiO_et) nanoparticles (NPs) by treating Ni(NO₃)₂.6H₂O with aqueous/ethanolic extracts of Elettaria cardamomum leaves; the same reaction was performed in the presence of graphene oxide (GO) to produce NiO_aq@GO and NiO_et@GO nanocomposites (NCs), respectively. The NMs were characterized by XRD, FT-IR, SEM, EDX, UV-visible spectroscopy, and TGA-DSC analysis. They were also subjected to electrochemical investigations and photocatalytic degradation of crystal violet (CV) dye. XRD analysis revealed the average crystallite sizes of 8.84-14.07 nm with a face-centered cubic form of NiO NPs and a hexagonal structure of their nano
