摘要

•Co9S8@MoS2 core-shell nanoparticles on porous carbon nanofibers are prepared.•Co-S-Mo heterojunction promotes the charge transfer between two phases.•S vacancies increase the localized state of Mo atoms for improved catalytic activity.•Overall water electrolytic cell requires a low potential of 1.41 V at 10 mA/cm2.
