The oxygen evolution reaction (OER) is considered as one of the major roadblocks for many renewable electrochemical energy technologies, such as water splitting, rechargeable metal‐air batteries. Thus the development of efficient and low‐cost OER electrocatalysts has achieved a lot of research and development attention. Aerogels, as featured by large surface area, high porosity, and self‐supportability, provide an excellent platform for the design of efficient electrocatalysts. This review summarizes the recent progress of the aerogel‐based design of catalysts in tackling the challenges in the field of OER electrocatalysis. The correlation between catalyst design strategy and catalytic performances is evaluated to provide a roadmap for the development of aerogel‐based OER electrocatalysts. Thereafter, the current state of our understanding of the application of the aerogel concept in OER electrocatalysis is provided, which could serve as a guide to the development of future aerogel electrocatalysts.
