Abstract

In this work, Co₉S₈ and N,S co-dopped carbon encapsulated WS₂ nanocomposites (Co₉S₈-N,S-C@WS₂) has been successfully prepared through a high-temperature carbonization of the precursor ZIF-67@WS₂ nanoparticles. The obtained Co₉S₈-N,S-C@WS₂ nanoparticles were confirmed to have a core-shell structure and uniform element distribution by TEM and element mapping. Its crystal structure was characterized by XRD, and the high specific surface areas with porous structure was characterized by BET tests. The as-prepared Co₉S₈-N,S-C@WS₂ nanoparticles exhibited a better ORR/OER/HER performance than single component. In this work, a novel idea for the preparation of functional nanocomposite materials could be provided.
