Cobalt incorporation and MoS2–NiS2 heterostructure synergistic for improving full water electrolysis efficiency

Cobalt doping MoS 2 /NiS 2 is first obtained using a chemical vapor vulcanization method. Cobalt doping further modified the electronic structure of MoS 2 /NiS 2 and modulated the electron density of catalytic sites, beneficial for HER and OER.
