“…Various heteroatoms, such as foreign cations, anions, and combinations of cation–anions, have been integrated as dopants into the structures of MoS 2 nanomaterials. For electrocatalytic applications, various doping techniques have been employed to ensure homogeneous doping of TMCs, including the hydrothermal/solvothermal method, , coprecipitation, , chemical vapor deposition (CVD), , thermal treatment, and in situ chemical reduction Both dry and wet doping methods are recognized for the synthesis of doped 1L MoS 2 materials .

The exhaustion of fossil fuels and resultant pollution issues have prompted the world to look to clean, nonpolluting hydrogen energy. The promising approach of the electrocatalytic hydrogen evolution reaction (HER) presents a solution for addressing energy and environmental challenges. Consequently, creating high-performance and cost-effective electrocatalysts is essential for the efficient decomposition of water. Molybdenum disulfide (MoS 2 ) has emerged as the most promising among potential electrocatalysts to replace platinum. However, only the edge-site of MoS 2 is active for HER due to the MoS 2 semiconductive nature and large inactive basal planes. Doping various substances, which significantly improves HER activity, can enhance MoS 2 's physical and chemical properties. Our Review encapsulates the latest strategies and research advancements in choosing heteroatomic-doped MoS 2 for hydrogen production. Various doping elements impart unique physical and chemical properties to MoS 2 . Specifically, doping with noble metals (e.g., Ag, Pt, Ru, Pd, Rh) and transition metals (e.g., Fe, V, Ni, Mn, Co, Zn, W), as well as codoping with multiple metal atoms (e.g., Cu-Pd, Pt-Te, Co-Nb, Ni-Co), can significantly enhance conductivity and introduce new active sites. These dopants are recognized for activating the basal plane of MoS 2 , thereby enhancing the HER activity. Furthermore, doping with nonmetallic elements (e.g., N, F, P, An, O) and their codoping combinations (e.g., O-P, N-F, Se-O), as well as the codoping of nonmetal and metal atoms (e.g., Co-Se, Co-P, N-Pt, Ru-O), is crucial for inducing phase conversions and improving stability. Each dopant contributes distinctively, either by enhancing the stability of MoS 2 , serving as a catalytic site, or broadening the pH range for effective HER. In this discussion, we further explore the current challenges and outlook of this promising area. Furthermore, we discuss existing challenges and promising guidelines for future research on the MoS 2 -based catalyst, offering advice to translation from laboratory research to large-scale industrial hydrogen production.

“…Additional LDHs, such as NiFeCr-LDH, 227 CoAl-LDH, 228 CeCoAl-LDH, 229 NiAl-LDH 230 and NiFe-LDH 197 have also been used to form MoS 2 /LDH heterostructures for OER, while MoS 2 heterostructures have been formed using cobalt phosphides, which are known as good OER electrocatalysts. 231 Nickel sulfides are also highly active for OER, and it is no surprise that they have been combined with MoS 2 to give heterostructures, such as MoS 2 /Ni 9 S 8 , 232 MoS 2 /Ni 3 S 2 , 233 MoS 2 /Fe 5 Ni 4 S 8 , 234 MoS 2 /NiS 2 combined with N-doped graphene foams, 235 Ni 3 S 2 /MoS 2 236 and MoSe 2 /Ni 3 S/FeOOH.…”

There has never been a more pressing need to develop sustainable energy systems as dramatic climate changes emerge across the world. Some of the effects can be alleviated by the development of efficient devices that are capable of producing hydrogen gas in an environmentally acceptable manner, which in turn can be employed as a clean fuel. In this context, the splitting of water is especially attractive. However, this technology requires the design of new cost-effective electrocatalytic materials. In this review, the progress made in the development of transition metal dichalcogenides (TMDs) and their composites as electrocatalysts for both acidic and alkaline electrolysis cells and as photocatalysts for the formation of hydrogen is described and discussed. Following a short introduction to the mechanisms of the electrochemical hydrogen and oxygen evolution reactions and the photoelectrochemical generation of hydrogen, an introduction to TMDs, their relevant general properties and the methods used in their synthesis are described. Then, the performance of various TMD-based materials in the electrochemical splitting of water is discussed, with a final brief overview of the application of TMDs in photoelectrochemical devices. Although challenges clearly remain, TMD-based materials are emerging as promising electrocatalysts and photoelectrocatalysts for the production of hydrogen.
