Resumen

A facile route is developed to boost the electrocatalytic activity of WS₂ by chemically unzipping WS₂ nanotubes to form WS ₂ nanoribbons (NRs) with increased edge content. Analysis indicates that the hydrogen evolution reaction activity is strongly associated with the number of exposed active edge sites. The formation of WS₂ NRs is an effective route for controlling the electrochemical properties of the 2D dichalcogenides, enabling their application in electrocatalysis.
