开发了一种简单的路线，以提高WS2的电催化活性的化学解链WS2纳米管形成WS2纳米带（NR）与增加的边缘内容。分析表明，析氢反应活性与暴露的活性边缘位点的数量密切相关。WS2 NRs的形成是控制2D二硫属化合物电化学性质的有效途径，使其能够在电催化中应用。
A facile route is developed to boost the electrocatalytic activity of WS2 by chemically unzipping WS2 nanotubes to form WS2 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.
