论文摘要
了解弹性应变在修饰催化反应速率中的作用对于催化剂设计至关重要，但是在实验上，这种作用通常与配体效应结合在一起。为了隔离应变效应，我们研究了外部施加的弹性应变对金属膜对氢进化反应（HER）的催化活性的影响。我们表明，弹性应变以可控且可预测的方式调节催化活性。理论和实验均以控制菌株的控制方式与她的火山图的定性预测以及D波段理论：Ni和Pt活性通过压缩加速，而CU活性通过张力加速了。通过从配体效应中分离弹性应变效应，该研究对弹性应变在控制电催化活性中的作用提供了更大的见解。
Understanding the role of elastic strain in modifying catalytic reaction rates is crucial for catalyst design, but experimentally, this effect is often coupled with a ligand effect. To isolate the strain effect, we have investigated the influence of externally applied elastic strain on the catalytic activity of metal films towards the hydrogen evolution reaction (HER). We show that elastic strain tunes the catalytic activity in a controlled and predictable way. Both theory and experiment show strain controls reactivity in a controlled manner consistent with the qualitative predictions of the HER volcano plot and the d-band theory: Ni and Pt activity were accelerated by compression, while Cu activity was accelerated by tension. By isolating the elastic strain effect from the ligand effect, this study provides a greater insight into the role of elastic strain in controlling electrocatalytic activity.
