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. 

Significance of the study:

This study introduces an efficient method to enhance supercapacitor performance by integrating MOF-derived CoFe₂O₄ nanoparticles with carbon nanofibers, resulting in a composite with high specific capacitance, energy density, and power density.

Summary of the study:

The paper details the synthesis of CoFe₂O₄@CNFs via electrospinning, demonstrating their superior electrochemical properties with a specific capacitance of 527 F/g, energy density of 16.58 Wh/kg, and power density of 234.93 W/kg.
