ABSTRACT: The rational design of multifunctional electrocatalysts requires synergistic integration of conductive scaffolds with redox-active components. Here, a hierarchical core-shell NiCo2S4 grown/anchored on Co9S8-loaded carbon nanofibers (NCS/CS/CNFs) was synthesized via an electrospinning and hydrothermal approach and systematically characterized. FESEM/TEM confirmed a core-shell nanofiber structure with a NiCo2S4 shell thickness of ~30-70 nm, increasing the fiber diameter to ~290 ± 30 nm, while BET analysis revealed a surface area of 24.84 m2 g-1 and pore volume of 0.042 cm3 g-1, surpassing CS/CNFs (6.12 m2 g-1) and NCS (4.85 m2 g-1).
