Hydrogen production by the electrolysis of water is a green and efficient method, which great significance for achieving sustainable development. Molybdenum disulfide (MoS2) promising electrocatalyst hydrogen evolution reaction (HER) due to its high electrochemical activity, low cost, abundant reserves. In comparison noble metal Pt, MoS2 has poorer performance in electrolysis. Therefore, further modifications need be developed aiming at improving catalytic performance. The present work summarizes modification strategies that have been past three years on from utilizing as following two aspects internal external modifications. former includes interlayer spacing, sulfur vacancy, phase transition, element doping, while latter heterostructure conductive substrate. If current gap this paper’s focus electrocatalytic addressed, will perform best acidic or alkaline media. addition that, also discusses challenges future development directions catalysts.

Metal-phase MoS2 (1T-MoS2) is considered a promising candidate as catalyst for the hydrogen evolution reaction (HER). However, instability of 1T-MoS2 limits its electrocatalytic activity. Herein, we first synthesized with excellent HER catalytic performance by simple one-pot hydrothermal strategy introducing d-electron-rich transition metal atom Ni into MoS2. A bimetallic monatomic (Pt@1T-MoS2–Ni) was also prepared modifying 1T-MoS2–Ni Pt single atoms (Pt SAs). Experiments show that electron transfer caused doping leads to 1T phase transition, and modification SAs further improves electrical conductivity. These two factors synergistically modulate electronic composition increase number reactive sites. In consequence, Pt@1T-MoS2–Ni exhibits significantly enhanced activity, achieving an overpotential low 76 mV at 10 mA/cm2 corresponding Tafel slope only 46 mV/dec. Moreover, current attenuation negligible within 12 h, surpassing This study offers ideas improving efficiency stability designs.
