Synthesis of ZnO nanoparticles through a simple wet chemical precipitation method

Abstract

The research on Zinc oxide nanoparticles has become very important on these days due to its unique property and wide range of applications in all the branches of science. In this study, we synthesized ZnO nanoparticles through a simple and cost-effective wet chemical precipitation approach. The XRD spectra revealed the hexagonal wurtzite structure in the prepared ZnO nanoparticles. The UV-Vis absorption peak of the as - prepared ZnO sample was identified at 301.2 nm and was observed to be blue shifted in comparison to the bulk counterpart. The transmittance analysis of the prepared ZnO sample showed very high transmittance to the visible range of light. The widening of the optical band gap was observed in the preparation ZnO sample. The band gap of the synthesized ZnO sample was found to be 3.7943 eV. The theoretical estimation of particle size in the prepared ZnO sample was performed using the Brus model and the particle size was estimated to be 4.38 nm. This study revealed the potential application of prepared ZnO nanoparticles as transparent electrode in solar cell.

NO2 and NH3 detection using work function measurement of solvothermal synthesised ZnO–NiO nanocomposites: a case study

“…For this, several metal oxide semiconductor (MOS) nanomaterials such as ZnO, SnO 2 , NiO, and TiO 2 have been studied [12][13][14][15]. The sensing materials have been realized using different chemical methods, such as hydrothermal [16], wet chemical route [17] and solvothermal [18]. Among them, the solvothermal technique offers the advantage of being eco-friendly and accordingly, is commercially exploited for the synthesis of well-defined nano-morphologies [19].…”

Influence of Sn doping on the optoelectronic properties of ZnO nanoparticles

“…17 The chemical solution process is one of the popular methods of synthesizing ZnO NPs, as in it, a simple precipitation method is used and requires simple chemicals. [17][18][19][20][21] In this process, the size, shapes, and purity are easily controllable by tuning fewer parameters. Mostly zinc salt precursors, the pH of the reaction mixture, and calcination temperature play a vital role in the properties of ZnO NPs.…”

STRUCTURAL PROPERTIES OF ZnO NANOPOWDERS SYNTHESIZED BY THERMAL DECOMPOSITION

“…The need to synthesise low-dimensional structures with certain characteristics has led to the development of a wide variety of methods for the synthesis of zinc oxide [12,13]. ZnO nanoparticles can be produced on a large scale by simple synthesis methods such as chemical precipitation [14], sol-gel method [15], solvothermal/hydrothermal synthesis methods [16,17] and others.…”
