Fe-Based Electrocatalysts for Oxygen Evolution Reaction: Progress and Perspectives

Feng, Chao, Faheem, M. Bilal, Fu, Jie, Xiao, Yequan, Li, Changli, Li, Yanbo·2020·ACS Catalysis

Abstract

Electrocatalytic oxygen evolution reaction (OER) is a core reaction responsible for converting renewable electricity into storable fuels; yet, it is kinetically challenging, because of the complex proton-coupled multielectron transfer process. Transition-metal-based electrocatalysts, which provide the possibility for the realization of low-cost, high-activity, and stable OER in alkaline solution, therefore have attracted significant research interest in recent years. A fundamental understanding of composition–structure–activity relationships for these electrocatalysts is essential to guide the design of practical electrocatalysts for industrial applications. With more advanced ex situ and in situ techniques to determine the active sites, there has been increasing evidence revealing the critical role of Fe in the high performance of Fe-containing transition metal-based electrocatalysts. Here, we present a critical review of recent progress in Fe-containing electrocatalysts for OER, highlighting the significant role of Fe in enhancing the OER activity. We outline the historical development of the Fe-containing electrocatalysts, summarize the conflicting viewpoints on catalytic active sites, and offer guidelines for more rigorous identification. The synthesis techniques and the major challenges in improving the intrinsic catalytic activity and stability are discussed. Finally, a perspective regarding emerging issues yet to be explored for developing OER electrocatalysts for practical applications are also provided.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
