Facile Synthesis and Electrochemical Properties of Perovskite‐type CeMnO ₃ Nanofibers

Abstract

Abstract Perovskite‐type CeMnO 3 nanofibers (NFs) were effectively synthesized via electrospinning and consequent calcination processes. The nanofibers with porous surface exhibit a high specific surface area of 103.88 m 2 g −1 with mesopores. The perovskite CeMnO 3 NFs were characterized by X‐ray diffraction, Raman spectroscopy, UV‐vis diffuse reflectance spectrum, and X‐ray photoelectron spectroscopy. The microstructure and morphology of CeMnO 3 were observed by scanning electron and transmission electron microscopes. The Energy‐dispersive X‐ray spectroscopy manifested the homogeneous distribution of cerium, manganese, and oxygen. The electrochemical properties of CeMnO 3 NFs were implemented using cyclic voltammetry and galvanostatic charge‐discharge in alkaline aqueous electrolyte. The Faradic redox reaction occurred at the electrode surface was precisely concluded. The specific capacitance of CeMnO 3 NFs was 159.59 F g −1 at the current density of 1 A g −1 . This research offers a new strategy to synthesize CeMnO 3 perovskite material for high‐performance supercapacitor, indicating its potential application as a supercapacitor electrode in energy storage devices.
