With the gradual depletion of fossil fuels and the deteriorating environment, it is urgent to develop clean and renewable energy technologies. In recent years, energy conversion and storage technologies, such as water electrolysis and rechargeable metal-air batteries, have attracted tremendous research attention. Oxygen evolution reaction(OER) is the core reaction of them. Remarkable OER electrocatalysts have been widely reported. The fabrication methods of electrocatalytic electrodes play a prominent role in the performance of the catalysts apart from the intrinsic activity of the catalysts. An increasing number of researchers are devoted to exploring the design and fabrication of high-performance OER electrodes. This review introduces the current fabrication strategies of OER electrodes, discusses their advantages and disadvantages with a summary of the latest research progress, and overviews the emerging approaches for new-type electrodes. Finally, future development in this field is prospected.
