Testing of new electrocatalytic cell for strain engineering of epitaxial membranes

A new electrocatalytic cell developed with the help of the Sample Environment unit will be tested for operando XRD analysis. The samples are crystalline La0.7Sr0.3MnO3 (LSMO) thin films on a plastic support. Strain engineering of the sample will be carried out by bending the support following it in-situ by XRD. The goal is to correlate the effect of strain on the corresponding electrocatalytic activity, specifically for oxygen evolution reaction (OER) in KOH electrolyte.在样品环境单元的协助下开发的新型电催化电池将用于原位X射线衍射（XRD）分析测试。样品为塑料基底上的结晶态La₀.₇Sr₀.₃MnO₃（LSMO）薄膜。样品的应变工程（strain engineering）将通过弯曲基底实现，并利用XRD对其进行原位监测。研究目标是关联应变对相应电催化活性的影响，特别是在氢氧化钾（KOH）电解液中氧析出反应（OER）的活性。
