论文摘要
氧演化反应（OER）被认为是电化学能量转化的关键反应，但动力学较慢，在电解机，金属电池和其他依赖水氧化中可持续质子的应用中应用。在这篇综述中，在碱性培养基中，在室温下对OER的外延钙钛矿氧化物的前景进行了审查，以了解对活动的系统趋势的基本见解。首先，我们彻底定义了钙钛矿结构及其参数空间。然后，调查用于使电催化分娩钙钛矿氧化物的合成方法进行调查，我们对可以组装的不同类型的电极进行了分类，以进行电催化研究。我们讨论了外延钙钛矿电极的半导体物理学及其对解释催化结果的后果。引入并相对讨论了OER的原型机制。对外延钙钛矿氧化物的OER研究进行了全面的调查，并以图形方式强调了选定的趋势。该综述以简短的看法是关于未来对外延钙岩氧化物系统进行电催化研究的机会。
The oxygen evolution reaction (OER) is considered a key reaction for electrochemical energy conversion but slow kinetics hamper application in electrolyzers, metal-air batteries and other applications that rely on sustainable protons from water oxidation. In this review, the prospect of epitaxial perovskite oxides for the OER at room temperature in alkaline media is reviewed with respect to fundamental insight into systematic trends of the activity. First, we thoroughly define the perovskite structure and its parameter space. Then, the synthesis methods used to make electrocatalytic epitaxial perovskite oxide are surveyed, and we classify the different kinds of electrodes that can be assembled for electrocatalytic investigations. We discuss the semiconductor physics of epitaxial perovskite electrodes and their consequences for the interpretation of catalytic results. Prototypical mechanisms of the OER are introduced and comparatively discussed. OER investigations on epitaxial perovskite oxides are comprehensively surveyed and selected trends are graphically highlighted. The review concludes with a short perspective on opportunities for future electrocatalytic research on epitaxial perovskite oxide systems.
