  "abstract": "A Mn–Co bimetallic nanoparticle-doped MIL-100(Fe) composite (Mn–Co/MIL-100(Fe)) was synthesized by solvothermal synthesis and evaluated for supercapacitor and dye-adsorption applications, with pristine MIL-100(Fe) used for direct comparison. The optical analysis showed a 1.85 eV band gap, indicating electronic interactions between the bimetallic species and the MOF matrix. Morphological studies confirmed the formation of hetero-interfaces, showing a transition from the spherical morphology of pristine MIL-100 to irregular polyhedral forms coated with Mn–Co nanoparticles. Additionally, Brunauer–Emmett–Teller (BET) analysis revealed a microporous structure having 17.71 m2 g−1 surface area, providing accessible pathways for electrolyte-ion diffusion. Cyclic voltammetry (CV) analysis revealed pseudo-capacitive behavior linked to faradaic redox reactions at the Mn and Co active sites, with power-law (b-value) and Dunn's method analyses showing a pronounced shift from diffusion-controlled charge storage in pristine MIL-100(Fe) (b = 0.45) to predominantly surface-controlled, capacitive-dominated behavior in the Mn–Co/MIL-100(Fe) nanocomposite (b = 0.99, up to ∼84% capacitive contribution). GCD measurements showed a specific capacitance of 167.9 F g−1 at 0.8 A g−1 for the Mn–Co/MIL-100(Fe) nanocomposite, approximately 2.5-fold higher than pristine MIL-100(Fe) (66.2 F g−1) under the same conditions. Cycling stability over 52 charge–discharge cycles showed no capacitance fading, with specific capacitance and coulombic efficiency both increasing to ∼170 F g−1 and ∼65.6%, respectively, indicative of progressive electrochemical activation. EIS analysis found a 31.87 Ω charge-transfer resistance, demonstrating moderate ion transport and charge-transfer properties within the porous framework. Beyond its pseudocapacitive performance, the Mn–Co/MIL-100(Fe) nanocomposite achieved ∼95% adsorptive removal efficiency toward malachite green dye, following pseudo-second-order kinetics (R2 = 0.9998) indicative of a chemisorption mechanism. These results indicate that Mn–Co incorporation modifies the MIL-100(Fe) properties, enhancing its potential for advanced multifunctional energy storage and water-remediation applications.",
