摘要

我们合成了用于水电解的负载Ir簇的单层WS2纳米片，并与WS2的硫化物离子形成的硫代硫酸盐种制备了独特的功能异质界面。原位XAFS测量表明，在析氢反应的界面活性位点，带正电的硫代硫酸盐和带负电的Ir团簇之间促进了水的解离。

Thiosulfate species promoting hydrogen evolution reaction at the heterointerface of Ir clusters-loaded WS2 nanosheets†

We synthesize Ir cluster-loaded monolayer WS₂ nanosheets for water electrolysis and fabricate unique functional heterointerfaces with thiosulfate species formed from sulfide ions of WS₂. In situ XAFS measurements reveal that water dissociation is promoted between positively charged thiosulfates and negatively charged Ir clusters at the interfacial active sites for hydrogen evolution reaction.
