Abstract

The oxygen evolution reaction (OER), as a four-electron transfer process with large overpotential loss that is also kinetically sluggish, is one of the most crucial electrochemical processes to convert renewable energy into chemical fuels. Ruthenium (Ru)-based electrocatalysts for the OER have several advantageous features including high activity, pH-universality and the lowest price in the noble metal family. However, the instability of Ru-based catalysts in the OER is a central hurdle limiting their widespread application. This review focuses on recent developments made in the field of Ru-based OER catalysts. In the coverage, first the characteristics of Ru-based OER catalysts such as the OER mechanism, intrinsic activity and stability issue are discussed. Then, recently reported Ru-related catalysts falling in the Ru metal and Ru compound subclasses are described with special emphasis being given to a discussion of activity/stability-enhancing strategies. Finally, several challenges and future perspectives in this field are summarized. It is anticipated that this review will promote a better understanding of Ru-based OER catalysts and lead to new strategies to design active and stable Ru-materials.

ru基析氧电催化剂的研究进展

析氧反应(OER)是将可再生能源转化为化学燃料的最关键的电化学过程之一，是一个具有较大过电位损失且动力学缓慢的四电子转移过程。钌基OER电催化剂具有活性高、ph值通用性强、价格低廉等优点。然而，钌基催化剂在OER中的不稳定性是限制其广泛应用的主要障碍。本文综述了近年来钌基OER催化剂的研究进展。本文首先讨论了钌基OER催化剂的特点，如OER机理、本征活性和稳定性问题。然后，描述了最近报道的钌金属和钌化合物亚类的钌相关催化剂，并特别强调了对活性/稳定性增强策略的讨论。最后，总结了该领域面临的挑战和未来的发展前景。期望本综述能促进对钌基OER催化剂的更好理解，并为设计活性稳定的钌材料提供新的策略。
