We report that one can gain active control of the electrocatalytic oxygen evolution reaction (OER) on Ni3Fe thin films via externally applied strains. The combination of theory and experiments shows that an elastic strain on the surface can tune the OER activity in a predictable way that is consistent with the d-band model. The OER overpotential can be lowered by uniaxial tensions and increased by compressions in a linear manner.
我们报告称，通过施加外部应变，可以对 Ni3Fe 薄膜的电催化析氧反应（OER）进行主动控制。理论和实验的结合表明，表面的弹性应变可以以与 d 带模型一致的可预测方式调节 OER 活性。通过单轴拉伸可以降低 OER 的过电势，而通过压缩可以以线性方式增加 OER 的过电势。
