Green Synthesis of Trimetallic Ni–Co–Mo incorporated into Biomass-Derived Porous Carbon for Advanced Supercapacitor Applications

This study reports two-step synthesis strategy employing bio-mass derived carbon obtained from cutch tree (Acacia catechu) bark which is subsequently incorporated into the nickel, cobalt, and molybdenum (NCMO) trimetallic oxide systems. A homogeneous dispersion of trimetallic oxides within the carbon matrix (NCM/AC), leads to notable alterations in both the surface morphology and crystalline characteristics of the synthesized nanocomposite. This Structural regulation effectively mitigates phase segregation and the enhanced accessibility of electrochemically active sites through structural regulation sites, thereby delivering a specific capacitance of 503 F g ^-1 at a current density of 1 A g ^-1 . Furthermore, the Hybrid supercapacitor device (HSD) based on the NCM/AC composite exhibits, retaining its electrochemical performance over 10,000 charge-discharge cycles at current density 5 A g ^-1 . Overall, our work demonstrates an environmentally benign and sustainable synthesis route that combines ternary metal oxides with biomass-derived activated carbon to produce efficient electrode materials suitable for advanced energy storage systems.
