Engineering the surface structure of MoS2 to preferentially expose active edge sites for electrocatalysis

摘要: Controlling surface structure at the atomic scale is paramount to developing effective catalysts. For example, the edge sites of MoS2 are highly catalytically active and are thus preferred at the catalyst surface over MoS2 basal planes, which are inert. However, thermodynamics favours the presence of the basal plane, limiting the number of active sites at the surface. Herein, we engineer the surface structure of MoS2 to preferentially expose edge sites to effect improved catalysis by successfully synthesizing contiguous large-area …
