MOF Derived CoFe2O4@Carbon Nanofibers for Supercapacitor Application

Abstract

This study presents the synthesis and electrochemical evaluation of MOF-derived CoFe2O4 nanoparticles anchored on carbon nanofibers (CoFe2O4@CNFs) for supercapacitor applications. By integrating hydrothermal and electrospinning techniques, we successfully fabricated CoFe2O4@CNFs with enhanced supercapacitive properties. The electrochemical performance of CoFe2O4@CNFs was rigorously assessed, revealing a remarkable specific capacitance of 527 F/g at a current density of 1 A/g. Additionally, the electrode demonstrated a power density of 234.93 W/kg and an energy density of 16.58 Wh/kg. These results highlight the synergistic effect of combining MOF-derived bimetallic transition metal oxides with carbon nanofibers, underscoring their potential in advancing supercapacitor technology. The findings suggest that CoFe2O4@CNFs can serve as a promising candidate for high-performance energy storage applications, offering a viable pathway to enhance the efficiency and capacity of supercapacitors.
