摘要

Perovskites attained considerable attention as a highly significant electrode for energy storage applications due to the dopant strategy of active rare-earth elements such as Nd which was doped to enhance the stability, specific capacitance, and excellent conductivity. The hydrothermal route was chosen to synthesize Nd-doped MnFeO3 (NMFO) perovskite electrode material. The morphology of Nd doped nanostructure was analysed by scanning electron microscopy (SEM) which showed agglomerated particles confining the dopant particles. Further, electrode characteristics have been observed using cyclic voltammetry (CV), GCD, and EIS studies. The cyclic voltammetry redox peaks indicated pseudocapacitor behaviour and the fabricated pure MFO compound exhibited capacitance of 776.0 F/g at 10 mV/s but the addition of Nd in MFO enhanced the capacitance (Cs) of the NMFO-doped material to 1070 F/g at a scan speed of 10 mV/s. Moreover, NMFO nanocomposite has excellent performance during charge–discharge process, demonstrating a capacitance of 1227 F/g at 1 A/g, while the series resistance (Rs) was measured as 1.09 Ω. Overall, the electrochemical performance of the compound consisting of MFO and dopant Nd shows its significant performance for energy storage/harvesting or supercapacitor as well as battery electrode and in many other electrochemical applications.
