Mechanism of sulfur vacancies and doping in 1 T'-MoS2 toward the evolution of hydrogen

Jing Zhou et al.

Summary: Due to its high activity, MoS2 shows promising potential in replacing Pt-based electrocatalysts for hydrogen evolution reaction (HER) applications. However, the poor conductivity and limited number of active sites in 2H-MoS2 hinder its practical use, and the overall performance of 1 T'-MoS2 still lags behind Pt-based electrocatalysts. In this study, doping and defect introduction methods were attempted to further enhance the HER performance of 1 T'-MoS2. Through first-principle calculations, it was found that Ni doping can further optimize the HER performance of 1 T'-MoS2.
