Strongly coupled Fe-doped NiS2/MoS2 composite for high-efficiency water splitting†
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.
