Abstract

Electrocatalytic water splitting has been identified as a potential candidate for producing clean hydrogen energy with zero carbon emission. However, the sluggish kinetics of oxygen evolution reaction on the anode side of the water-splitting device significantly hinders its practical applications. Generally, the efficiency of oxygen evolution processes depends greatly on the availability of cost-effective catalysts with high activity and selectivity. In recent years, extensive theoretical and experimental studies have demonstrated that cobalt (Co)-based nanomaterials, especially low-dimensional Co-based nanomaterials with a huge specific surface area and abundant unsaturated active sites, have emerged as versatile electrocatalysts for oxygen evolution reactions, and thus, great progress has been made in the rational design and synthesis of Co-based nanomaterials for electrocatalytic oxygen evolution reactions. Considering the remarkable progress in this area, in this timely review, we highlight the most recent developments in Co-based nanomaterials relating to their dimensional control, defect regulation (conductivity), electronic structure regulation, and so forth. Furthermore, a brief conclusion about recent progress achieved in oxygen evolution on Co-based nanomaterials, as well as an outlook on future research challenges, is given.

氧进化反应钴基电催化剂的电子和活性位点工程研究进展
电催化水分离被认为是生产零碳排放清洁氢能的潜在候选方法。然而,水分离装置阳极侧氧进化反应的缓慢动力学极大地阻碍了其实际应用。一般来说,氧进化过程的效率在很大程度上取决于是否有高活性和高选择性的经济型催化剂。近年来,大量的理论和实验研究表明,钴(Co)基纳米材料,尤其是具有巨大比表面积和丰富不饱和活性位点的低维钴基纳米材料,已成为氧进化反应的多功能电催化剂,因此,用于电催化氧进化反应的钴基纳米材料的合理设计和合成已取得了重大进展。考虑到这一领域的显著进展,我们在这篇及时的综述中重点介绍了 Co 基纳米材料在尺寸控制、缺陷调节(导电性)、电子结构调节等方面的最新进展。此外,我们还简要总结了钴基纳米材料在氧进化方面取得的最新进展,并展望了未来的研究挑战。
