Abstract
Pure Lanthanum Ferrite (LaFeO3) nanoparticles and Lanthanum Magnesium Ferrite (LaMgxFe1-xO3) nanocomposites have been prepared by the sol-gel auto-combustion method. The structural and morphological properties were investigated by X-ray diffraction (XRD), Scanning electron microscopy (SEM) and energy dispersive X-ray (EDAX) spectroscopy. Powder XRD studies revealed that the samples are pure orthorhombic perovskite crystals with a size of around 20–50 nm. The FT-IR spectra of pure and composites was confirmed the formation perovskite structure. It has been discovered that composites material functions as an electrode in supercapacitors after its electrical characteristics have been examined by galvanostatic charging and discharging (GCD), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) with a 2 M KOH electrolyte.
采用溶胶-凝胶自燃烧法制备了纯镧铁氧体(LaFeO3)纳米粒子和镧镁铁氧体(LaMgxFe1-xO3)纳米复合材料。通过 X 射线衍射(XRD)、扫描电子显微镜(SEM)和能量色散 X 射线(EDAX)光谱对其结构和形态特性进行了研究。粉末 X 射线衍射研究表明,样品是纯正的正交闪长岩晶体,大小约为 20-50 纳米。纯样品和复合材料的傅立叶变换红外光谱证实了包晶结构的形成。通过在 2 M KOH 电解液中进行电静态充放电 (GCD)、循环伏安 (CV) 和电化学阻抗谱 (EIS) 测试,发现复合材料可用作超级电容器的电极。
