Fe-Based Electrocatalysts for Oxygen-Evolution Reaction

Fe-Based Electrocatalysts for Oxygen-Evolution Reaction

Yanyan Yang, Shasha Li, Xuli Ma, Xiaogang Hao, Abuliti Abudula, Guoqing Guan

Iron is the most common element by mass on the earth, and iron-based catalysts have attracted remarkable attention on account of their low cost as well as high activity. In the water electrolysis process, besides conventional precious metal-based catalysts, iron (Fe)-based materials are also becoming most promising catalysts for oxygen evolution reaction (OER). In this chapter, the states of the art of main Fe-based electrocatalysts, including their preparation methods, performances, and the strategies for the activity improvement are reviewed. In addition, the catalytic mechanisms of Fe-based electrocatalysts are also analyzed for giving insight into the intrinsic active catalytic sites. Finally, future research on how to enhance the performance of Fe-based OER electrocatalysts is discussed.
