Developing earth-abundant and highly effective electrocatalysts for electrocatalytic water splitting is a prerequisite for the upcoming hydrogen energy society. Recently, manganese-based materials have been one of the most promising candidates to replace noble metal catalysts due to their natural abundance, low cost, adjustable electronic properties, and excellent chemical stability. Although some achievements have been made in the past decades, their performance is still far lower than that of Pt. Therefore, further research is needed to improve the performance of manganese-based catalytic materials. In this review, we summarize the research progress on the application of manganese-based materials as catalysts for electrolytic water splitting. We first introduce the mechanism of electrocatalytic water decomposition using a manganese-based electrocatalyst. We then thoroughly discuss the optimization strategy used to enhance the catalytic activity of manganese-based electrocatalysts, including doping and defect engineering, interface engineering, and phase engineering. Finally, we present several future design opportunities for highly efficient manganese-based electrocatalysts.
开发丰富的地球资源和高效的电催化剂用于电催化水分解是即将到来的氢能社会的前提。最近，由于其丰富的自然资源、低成本、可调节的电子特性和优异的化学稳定性，基于锰的材料已成为最有前途的替代贵金属催化剂的候选材料之一。尽管在过去几十年中已经取得了一些成就，但它们的性能仍然远低于 Pt。因此，需要进一步研究以提高基于锰的催化材料的性能。在这篇综述中，我们总结了基于锰的材料作为电解水析催化剂的应用研究进展。我们首先介绍了使用基于锰的电催化剂进行电催化水分解的机理。然后，我们深入讨论了优化基于锰的电催化剂催化活性的策略，包括掺杂和缺陷工程、界面工程和相工程。最后，我们提出了几种高效基于锰的电催化剂的未来设计机会。
