Abstract
AbstractPerovskite‐type CeMnO3 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 m2 g−1 with mesopores. The perovskite CeMnO3 NFs were characterized by X‐ray diffraction, Raman spectroscopy, UV‐vis diffuse reflectance spectrum, and X‐ray photoelectron spectroscopy. The microstructure and morphology of CeMnO3 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 CeMnO3 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 CeMnO3 NFs was 159.59 F g−1 at the current density of 1 A g−1. This research offers a new strategy to synthesize CeMnO3 perovskite material for high‐performance supercapacitor, indicating its potential application as a supercapacitor electrode in energy storage devices.
