- Abstract
Ca1-xSrxMnO3 (x = 0, 0.1, 0.2) nanoparticules were synthesized by the coprecipitation method. The structural analysis reveals the presence of Octahedral coordination of MnO4. Fourier transform infrared spectroscopy (FTIR) spectra of MnO4 show the occurrence of O-Mn-O vibrational mode at around 590 cm-1. The XRD indicates that the samples are Rhombohedral lattice. The differential and thermo gravimetric analysis, curve obtained from the composition x=0.1,it has distinct pure phase at 600°C. The study of electrochemical behavior was carried out by cyclic Voltammetry (CV) and impedance spectroscopy (EIS).Show that the apparent electrochemical activity improves by increasing the strontium concentration. This is due to the particle size effect of strontium.
