Stabilizing Hydrogen Adsorption through Theory-Guided Chalcogen Substitution in Chevrel-Phase Mo6X8 (X=S, Se, Te) Electrocatalysts

“…While Pt is currently championed as the most efficient HER catalyst owing to its nearly thermoneutral H adsorption, scalability of systems based upon noble metals is hindered by high production costs engendered by elemental scarcity. , Many cases in nature (e.g., hydrogenase and nitrogenase enzymes) have succeeded in achieving favorable Δ G H with earth-abundant catalyst compositions that often include non-precious transition-metal chalcogenides with Fe, Ni, and Mo at their active sites. , These revelations highlighted the promise of inorganic analogues such as MoS 2 , where H adsorption at edge sites indeed approaches the Δ G H of Pt. , This observation is consistent with the popular d-band center model which suggests that HER reactivity correlates with the density of transition-metal d states near the Fermi level of the catalyst . Recent advances have identified a range of transition-metal dichalcogenides such as WS 2 , , FeS 2 , , CoS 2 , , WSe 2 , MoSe 2 , − CoSe 2 , , and CoTe 2 , as active catalysts for HER. It is believed that the HER activity of this family of compounds relies on the negatively polarized chalcogenide anions, which results in lower free-energy barriers for proton adsorption …”

Immobilized Precursor Particle Driven Growth of Centimeter-Sized MoTe2 Monolayer

“…23,24 More attractively, semimetal MoTe 2 exhibits a huge discrepancy from normal TMDCs in many characteristics, such as the smallest free energy difference between the semiconducting phase and semimetallic phase in phase-engineering and the giant magnetoresistance in magnetic properties. 25,26 Semimetallic MoTe 2 has been confirmed to be a type-II Weyl semimetal on account of its unique surface Fermi arcs. 27,28 The unusual coexistence of large spin Hall angle and robust spin diffusion over long distances at room temperature makes MoTe 2 an excellent candidate for spintronic applications.…”

“…Two-dimensional transition-metal dichalcogenides (TMDCs) have been widely investigated owing to their excellent physical properties. The quantum spin Hall effect, valley polarization effect, two-dimensional superconductivity, excellent photoelectric performance, and many other properties have been discovered in these ultrathin materials in the past few years. − Among these, the spintronics and phase-engineering applications have made MoTe 2 a particularly interesting material in recent years. − For instance, MoTe 2 can be stabilized in both monoclinic and hexagonal crystal orientation in the natural state and has semimetallic and semiconductor properties, respectively. , More attractively, semimetal MoTe 2 exhibits a huge discrepancy from normal TMDCs in many characteristics, such as the smallest free energy difference between the semiconducting phase and semimetallic phase in phase-engineering and the giant magnetoresistance in magnetic properties. , Semimetallic MoTe 2 has been confirmed to be a type-II Weyl semimetal on account of its unique surface Fermi arcs. , The unusual coexistence of large spin Hall angle and robust spin diffusion over long distances at room temperature makes MoTe 2 an excellent candidate for spintronic applications . To realize the above-mentioned potential applications, a stable growth strategy for the large-area semimetal MoTe 2 monolayer is urgently required.…”
