MoS2 and its derivates have been regarded as a promising
catalyst for the hydrogen evolution reaction (HER), and their edge
sulfur sites are key factors for the HER performance. Here, we develop
a facile strategy to grow nonstoichiometric molybdenum sulfide (MoSx) with more active sulfur sites on porous
N-doped graphene (MoSx@CN). Experiments
demonstrate that the introduction of porous N-doped graphene not only
facilitates the fast transfer of charge and the efficient infiltration
of the electrolyte but the N dopants could be used as the nucleation
sites for MoSx to possess more active
bridging S22– sites. Consequently, the
obtained MoSx@CN catalyst possesses an
outstanding HER activity, which shows an overpotential of 256 mV at
100 mA cm–2 with a Tafel slope of 49 mV dec–1. This study provides a new strategy to optimize transition
metal dichalcogenide-based catalysts for energy-related applications.
