dc.description.abstract |
ZnO nanoparticles have been synthesized using pineapple peel extract
(ananascomosus) with various precursor to extract volume ratio. The samples resulted
from the synthesis of ZnO nanoparticles were characterized using Ultraviolet-Visible
(Uv-Vis) Spectroscopy, X-Ray Diffractometer (XRD), Fourier Transform Infra-Red
(FTIR) and Scanning Electron Microscopy (SEM). The UV-Vis spectrum of the
sample shows strong absorption peaks that occurs over a range of wavelengths of
300-380 nm for all samples. The diffraction pattern of the XRD exhibits seven
diffraction peaks that correspond to the hkl of hexagonal wurtzite structure. The
highest peak intensity (the strongest line) is in the crystal plane (101). The FTIR
spectrum displays absorbance peaks that represent the involvement of N-H and O-H
functional groups derived from polyphenol compounds in the synthesis process. SEM
images show the morphology of ZnO sample are mixed spherical and flower-like
shape. The size of the nanoparticles obtained exceeds 100 nm and shows the evidence
of agglomeration. The volume of the extract affects the energy gap, the size and
shape of the ZnO particles. |
