Abstract:
Human’s quest for innovation, finding solutions to problems, and upgrading the industrial yield
with energy efficient and cost effective materials has opened the avenues of nanotechnology.
Among various nanoparticles, Zinc oxide nanoparticles (ZnONPs) has broad applications in
various areas. Green synthesis is an alternative to conventional physical and chemical methods.
Green synthesis of nanoparticles is gaining importance due to its cost-effectiveness, reduction of
toxic chemicals and extensive antimicrobial activity. Green synthesis of zinc oxide nanoparticles
(ZnONPs) using agro waste materials particularly goat faecal matter as a reducing agent.
Synthesized ZnONPs were evaluated for particle size, absorbance and photoluminescence
properties using UV–visible spectroscopy. Agro-waste based green synthesized ZnONPs possess
small sized particles, which enhances the good antimicrobial effect. This research will also
provide a means of transforming goats wastes which would otherwise contaminate the
environment into ZnONPs whose optical properties is studied for optoelectronic uses.
