Abstract
Zinc oxide nanoparticles were synthesized by employing solution combustion method
using environmental friendly Cellophyllum innophyllum seed powder as fuel. Phase
purity, crystallite size were determined from X-ray diffraction (XRD). Organic species
attached to the surface of the nanoparticle were identified using Fourier transform
infrared spectroscopy (FTIR). Morphological studies were performed using TEM and
SEM.
Bandgap increased with decreasing particle size as confirmed from the diffuse reflectance
spectroscopy (DRS) white light luminescence capabilities of ZnO NPs were studied
using photoluminescence spectroscopy. In vitro antibacterial activity studies and
catalytic property for the conversion of pumpkin seed oil into biodiesel were performed.
