The exhaustion of fossil fuels and resultant pollution issues have prompted the world to look clean, nonpolluting hydrogen energy. promising approach electrocatalytic evolution reaction (HER) presents a solution for addressing energy environmental challenges. Consequently, creating high-performance cost-effective electrocatalysts is essential efficient decomposition water. Molybdenum disulfide (MoS2) has emerged as most among potential replace platinum. However, only edge-site MoS2 active HER due semiconductive nature large inactive basal planes. Doping various substances, which significantly improves activity, can enhance MoS2's physical chemical properties. Our Review encapsulates latest strategies research advancements in choosing heteroatomic-doped production. Various doping elements impart unique properties MoS2. Specifically, with noble metals (e.g., Ag, Pt, Ru, Pd, Rh) transition Fe, V, Ni, Mn, Co, Zn, W), well codoping multiple metal atoms Cu-Pd, Pt-Te, Co-Nb, Ni-Co), conductivity introduce new sites. These dopants are recognized activating plane MoS2, thereby enhancing activity.

Hydrogen production via water electrolysis defines the novel energy vector for achieving a sustainable society. However, true progress of given technology is hindered by sluggish and complex hydrogen evolution reaction (HER) occurring at cathodic side system where overpriced scarce Pt-based electrocatalysts are usually employed.
