Carbon is predominantly used in zinc-ion hybrid capacitors (ZIHCs) as an electrode material. Nitrogen doping and strategic design can enhance its electrochemical properties. Melamine formaldehyde resin, serving a hard carbon precursor, synthesizes nitrogen-doped porous after annealing. Incorporating transition metal catalysts like Ni, Co, Fe alters the morphology, pore structure, graphitization degree, nitrogen types/proportions. Electrochemical tests reveal superior capacitance of 159.5 F g-1 at scan rate 1 mV s-1 performance Fe-catalyzed N-doped (Fe-NDPC). Advanced analysis shows Fe-NDPC's high graphitic content boosting electric double-layer (EDLC) pseudocapacitance. Its abundant micro- mesopores increase surface area fourfold compared to non-catalyzed samples, favoring EDLC fast electrolyte transport. This study guides catalyst application materials for supercapacitors, illuminating how influence structure performance.

Abstract Hierarchical porous carbon materials hold great potential in electrochemical energy storage, yet their efficient fabrication still faces numerous challenges. Herein, we successfully prepared hierarchical with high specific surface area, broad pore size distribution, and interconnected structures by direct co-pyrolysis of wheat straw potassium hydroxide, leveraging the natural reticular structure straw. As an electrode material for symmetric supercapacitors, CS-800 exhibited excellent performance, retaining 96.94% its initial capacity after 20,000 cycles at current density 1 A g⁻ achieving nearly 100% Coulombic efficiency. Furthermore, to expand application scope, assembled a zinc-ion capacitor using as cathode, which delivered 173 mAh . The channels significantly enhanced ion transport storage capabilities optimized adsorption desorption processes charge carriers. This study demonstrates that preparation high-value-added from biomass waste holds prospects.
