Despite the dedicated search for novel catalysts for fuel cell applications, the intrinsic oxygen reduction reaction (ORR) activity of materials has not improved significantly over the past decade. Here, we review the role of theory in understanding the ORR mechanism and highlight the descriptor-based approaches that have been used to identify catalysts with increased activity. Specifically, by showing that the performance of the commonly studied materials (e.g., metals, alloys, carbons, etc.) is limited by unfavorable scaling relationships (for binding energies of reaction intermediates), we present a number of alternative strategies that may lead to the design and discovery of more promising materials for ORR.

了解氧还原反应中的催化活性趋势

尽管专门寻求用于燃料电池应用的新型催化剂，但是材料的固有氧还原反应（ORR）活性在过去十年中并未显着改善。在这里，我们回顾了理论在理解ORR机理中的作用，并重点介绍了基于描述符的方法，这些方法已被用于鉴定活性增加的催化剂。具体而言，通过显示常用研究材料（例如金属，合金，碳等）的性能受到不利的比例关系（用于反应中间体的结合能）的限制，我们提出了许多替代策略，这些方法可能会导致设计和发现更有前景的ORR材料。
