Abstract

Abstract MnO2 is found in different crystal phases and morphologies depending upon the linkage of basic octahedral units [MnO6]. Here in this article, the MnO2 nanoparticles with pure α-phase, mixed α + β-phase and β-phase were prepared via wet redox method. Structural analysis of all prepared MnO2 based nanoparticles was done using X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopic studies. XRD analysis revealed the phase transformation from α to β phase of MnO2 as a function of dopant. XRD data was also used to determine other structural parameters, crystallite size etc. The crystallite size was found
