The quest to identify precious metal free hydrogen evolution reaction catalysts has received unprecedented attention in the past decade. In this Review, we focus our recent developments reactions acidic and alkaline electrolyte owing their relevance commercial near-commercial low-temperature electrolyzers. We provide a detailed review critical analysis of catalyst activity stability performance measurements metrics commonly deployed literature, as well best practices for experimental (both half-cell three-electrode configurations two-electrode device testing). particular, discuss transition from laboratory-scale (HER) those single cells, which is aspect crucial scaling up laboratory industrial settings but often overlooked. Furthermore, numerous design strategies across HER literature. Subsequently, showcase some most investigated families catalysts; molybdenum disulfide-based, phosphides, carbides electrolyte; nickel phosphides alkaline. This includes comprehensive comparing between several materials highlighting stagnation with regards enhancing intrinsic catalysts. Finally, summarize future directions recommendations field area electrocatalysis.

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. Furthermore, nonmetallic N, F, P, An, O) their combinations O-P, N-F, Se-O), nonmetal Co-Se, Co-P, N-Pt, Ru-O), crucial inducing phase conversions improving stability. Each dopant contributes distinctively, either by stability serving catalytic site, or broadening pH range effective HER. In this discussion, we further explore current challenges outlook area. discuss existing guidelines future on MoS2-based catalyst, offering advice translation from laboratory large-scale industrial

Abstract Benefiting from similar hydrogen bonding energy to Pt and much lower price compare with Pt, Ru based catalysts are promising candidates for electrocatalytic evolution reaction (HER). The catalytic activity of nanoparticles can be enhanced through improving their dispersion by using different supports, the strong metal supports interaction further regulate performance. In addition, single‐atom (SACs) almost 100% atomic utilization attract great attention coordinative atmosphere single atoms adjusted supports. Moreover, syngenetic effects improve performance catalysts. this review, progress HER electrocatalysts summarized according existing forms, including (NPs), (SAs) combination both NPs SAs. common such as carbon materials, oxides, phosphides sulfides classified clarify active centers. Especially, possible mechanisms reasons improved discussed experimental results theoretical calculations. Finally, some challenges opportunities prospected facilitate development HER.

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. Therefore, efficient platinum group metals (PGMs)-free to carry out HER with accelerated kinetics urgently demanded. In this scenario, molybdenum disulfide (MoS2) owing efficacious structural attributes optimum hydrogen-binding free (ΔGH*) emerging as reliable alternative PGMs. performance MoS2-based still far away from benchmark performance. The activity MoS2 can be improved engineering parameters i.e., doping, defects inducement, modulating electronic structure, stabilizing 1T phase, creating nanocomposites, altering morphologies using appropriate fabrication pathways. Here, we have comprehensively reviewed majority scientific endeavors published in recent years uplift different methods. Advancements major strategies including hydrothermal synthesis methods, chemical vapor deposition, exfoliation techniques, plasma treatments, methodologies, etc. tune hence their ultimate influence on electrocatalytic acidic and/or alkaline media been thoroughly discussed. This study provide encyclopedic insights about routes that pursued improve electrocatalysts.
