In the present work, we describe a low-cost and simple procedure for
biosynthesis of Zinc oxide nanoparticles (ZnO NPs) using different volumes from
red Cabbage extract. Zinc acetate hydrate [Zn(OAc)2.2H2O] solution was
used as a precursor to synthesize Zinc oxide nanoparticles. The prepared ZnO
nanoparticles were characterized using scanning electron microscopy (SEM),
Elemental Dispersion Analysis of X-ray (EDAX), Fourier transform infrared
spectroscopy (FTIR), X-Ray diffraction (XRD) and Brunauer–Emmet-Teller (BET)
surface area. The suitable volume of plant extract can effectively regulate the
morphology, particle size and distribution of ZnO, and form more mesopores.
FT-IR spectra revealed the functional groups and the presence of protein as the
reducing/capping agents for surrounding the ZnO nanoparticles. The average
crystallite size of the as prepared ZnO samples (calculated by Scherrer formula)
is about 35 nm, 28 nm, 23 nm, and 16 nm for samples obtained in the presence of
5, 10, 15 and 20 ml of the aqueous extracts, respectively. The EDAX analysis,
confirmed the presence of metallic zinc oxide in biosynthesized ZnO NPs.
