Synthesis and characterization of MnO2 Nanoparticles using Co-precipitation Technique

Abstract

Manganese dioxide nanoparticles were synthesized using co-precipitation method for 0.1 mol and 0.2mol concentration, which is the simple way to prepare the aqueous solution. The dried samples were characterized using various techniques such as XRD, SEM, FTIR and UV-Visible spectroscopy. The average particle size of manganese oxide nanoparticles was calculated from the XRD study. The Morphology and size of the synthesized MnO2 particles are studied by scanning electron microscopy (SEM). The band gap energy for MnO2 is found using UV-Visible spectroscopy. The FT-IR spectra of MnO2 shows the peaks corresponding to stretching and bending vibration. There are large number of potential applications of MnO2 metal nanoparticles such as in the field of electrode materials in different rechargeable batteries, biosensors, coatings, nanofibres, nanowires and bioscience applications.
