Metal-based catalysts play a crucial role in electrocatalysis because their superior electrocatalytic performance. The surface electronic structure of metal catalysts exerts a great influence on the electrocatalytic activity. Strain engineering can be used to tune the electronic structure of metal catalysts and adjust the interaction between metal surface and the adsorbate, thereby improving the electrocatalytic performance. In this paper, the general strategies of strain introduction in metal catalysts were summarized. The relationship of strain-electronic structure-electrocatalytic performance was revealed based on theoretical calculation and experimental results. The development trend of strain engineering tailored electrocatalytic performance was also commented simply.
