Abstract
We demonstrated correlations between mechanically bent tensile-strain- induced two-dimensional MoS2 nanosheets (NSs) and their electrochemical activities toward the hydrogen evolution reaction (HER). The tensile-strain-induced MoS2 NSs showed significantly steeper polarization curves and lower Tafel slopes than the strain-free ones, which is consistent with the simple d-band model. Furthermore, the mechanical strain increased the electrochemical activities of all the NSs toward the HER except those loaded with high MoS2 mass. Mechanically bending MoS 2 NSs to induce tensile strain enables the production of powerful, efficient electrocatalysis systems for evolving hydrogen.
