Abstract

We developed a simple method to fabricate a strongly coupled Fe-doped NiS₂/MoS₂ composite by introducing dual confinement effects during the vapor vulcanization of precursors, which involves the controlled release of metal species and the in situ formation of an N-doped carbon layer. The Fe-doped NiS₂/MoS₂ composite exhibited a much-enhanced hydrogen/oxygen evolution reaction performance.
