抄録

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.
