Abstract

Ca1-xSrxMnO3 (x = 0, 0.1, 0.2) nanoparticules were synthesized by the co- precipitation 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.

钙钛矿型Ca1-xSrxMnO3的性质与特性

采用共沉淀法合成了Ca1-xSrxMnO3 (x = 0,0.1, 0.2)纳米颗粒。结构分析表明MnO4存在八面体配位。MnO4的傅里叶变换红外光谱(FTIR)显示在590 cm-1附近出现O-Mn-O振动模式。XRD分析表明，样品为菱面体晶格。通过差示和热重分析，得到组分x=0.1的曲线，在600℃时具有明显的纯相。采用循环伏安法(CV)和阻抗谱法(EIS)对其电化学行为进行了研究。结果表明，随着锶浓度的增加，表观电化学活性有所提高。这是由于锶的粒度效应。
