Structure, Synthesis and Applications of ZnO Nanoparticles: A Review

Abstract

Nanotechnology deals with the creation and utilization of materials at a
nanoscale. Nanoparticles, in general, possess enormous surface area per unit volume and
have explicit characteristics. Zinc oxide (ZnO) - based nanomaterials have been recognized
to be of countless uses for numerous important requests from the beginning of nanoscience
as a result of the great quantity of zinc element and the comparatively simple adaptation of
its oxide to nanostructures. Currently, ZnO as nanoparticles, nanowires, nanofibers in
addition to other classy nanostructures occurs amongst the innovator nanomaterials utilized
in solar cell systems, fuel cells, water purification and biomedical fields. ZnO nanoparticles
had been a research target for many investigations because of their vast band-gap and
extraordinary exciton binding energy. The performance of ZnO nanoparticles is completely
different from those of corresponding bulk materials, through enhancing the properties and
using lesser amount of materials, which leads to price reduction. The main purpose behind
this review article is to give a deep view on structure, synthesis and applications of ZnO
nanoparticles prepared through various approaches to give the reader a comprehensive
understanding.
