论文摘要
在实验和理论上研究了EX现有电子电导率，氧空位含量，含氧电势（EFB）和氧气进化反应（OER）活性之间的相关性。发现所有这些参数都会影响OER活性。但是，它们都不是在确定电催化活性中起着至关重要的作用。一种单个物理化学特性与OER活性的相关性总是呈现偏差点，表明确实存在这种二维相关性的限制。然而，可以考虑考虑其他物理化学特性及其与OER活性的相关性，可以解释这些偏差。因此，这项工作旨在同时将OER活性与几种理化材料特性联系起来。 OER/多题词关系的概念代表了在高度活性氧气演化催化剂的搜索和设计中的显着进步，以寻求水电解液中有效的阳极。
The correlation between ex situ electronic conductivity, oxygen vacancy content, flat-band potential (Efb), and the oxygen evolution reaction (OER) activity for a wide range of perovskite compositions are investigated experimentally and theoretically. It is found that all of these parameters can affect the OER activity; however, none of them alone play a crucial role in determining the electrocatalytic activity. The correlation of one single physicochemical property with the OER activity always presents deviation points, indicating that a limitation does exist for such 2-dimensional correlations. Nevertheless, these deviations can be explained considering other physicochemical properties and their correlation with the OER activity. Hence, this work aims in simultaneously linking the OER activity with several physicochemical materials properties. The concept of the OER/multidescriptor relationship represents a significant advancement in the search and design of highly active oxygen evolution catalysts, in the quest for efficient anodes in water electrolyzers.
