Hydrogen evolution: Not living on the edge

Nature Energy, Published online: 31 July 2017; doi:10.1038/nenergy.2017.132

Transition-metal dichalcogenides are appealing catalysts for H₂ generation from water. They tend to rely on scarce edge sites, rather than the more abundant basal-plane sites, to drive catalysis. Now, guided by computation, H-TaS₂ and H-NbS₂ are proposed as highly basal-plane-active catalysts that improve with electrochemical cycling.

过渡金属二卤化物是从水中生成H _2的有吸引力的催化剂。他们倾向于依靠稀缺的边缘位点，而不是依靠更丰富的基面位点来驱动催化作用。现在，在计算的指导下，提出了H- TaS ₂和H -NbS ₂作为具有高的基面活性催化剂，并随着电化学循环而提高。
