Synergistic effect of cocatalytic NiSe₂ on stable 1T-MoS₂ for hydrogen evolution.

ABSTRACT: Robust and economical catalysts are imperative to realize the versatile applications of hydrogen. Herein, a 1T-MoS₂/N-doped NiSe₂ composite was rationally synthesized via a solvothermal method, in which the MoS₂ nanosheets have a stable 1T phase structure, and the NiSe₂ nanoparticles serve as a cocatalytic support for MoS₂. The nonnegligible electronic couplings between NiSe₂ and MoS₂ could facilitate the optimization of their electronic structure and then improve the hydrogen adsorption. What is more, the nitrogen dopants in the NiSe₂ nanoparticles could intensify the intercalation of ammonium ions in the 1T-MoS₂ nanosheets, and further enlarge their interlayer spacing, thus the elect
