The Cover Feature shows decoupled water splitting electrolysis with the assistance of redox mediators. Representative redox mediators, including ferrocene‐derivatized ammonium chloride, sodium ferrocyanide, phosphmolybdic acid, and hydroquinone sulfonate, are able to decouple the two half‐reactions of water electrolysis. Consequently, hydrogen and oxygen can be produced at different times in different places with much lower voltage inputs for each step, allowing great flexibility in the design of water splitting electrolyzers. More information can be found in the Minireview by X. Liu et al. on page 2157 in Issue 8, 2019 (DOI: 10.1002/celc.201801671).
