Two-dimensional Fe-MOF and bimetallic NiFe-MOFs with different Ni : Fe ratios for superior electrochemical performance in supercapacitor applications.

ABSTRACT: Supercapacitors (SCs) are garnering significant attention owing to their remarkable power density. Transition-metal-based MOFs have abundant valence states, which contribute to their superior stability, high energy density, and high power density. In this study, monometallic Fe-BDC MOF and bimetallic NiFe-BDC MOFs were synthesized with different molar ratios and examined for their application in supercapacitors. SEM-coupled EDX, BET, and XRD analyses were performed to determine their morphologies and microstructures. The electrodes were evaluated through cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), and electrochemical impedance spectroscopy (EIS) measurements in a 1 M KOH aqueous electrolyte. The Ni₁₀Fe₁-BDC MOF electrode exhibited the highest capaci
