Cover Story: The coupling of renewable energies with electrochemical water splitting to convert surplus electrical energy into storable and multipurpose hydrogen seems highly desirable. The oxygen evolution reaction (OER) is the anodic half-reaction of water electrolysis and the limiting part due to a high kinetic barrier. Electrode materials (i.e., electrocatalysts) based on scarce and costly noble metals are the best-performing OER catalysts. For large-scale water electrolysis, the use of earth-abundant electrocatalysts with a good OER performance remains a major challenge. Porous metal–organic frameworks (MOFs) can be employed as sacrificial agents to construct efficient nano- and high-surface-area electrocatalysts. This work focuses on nickel-based MOFs for the formation of OER electrocatalysts. View this paper
