In article number 2001059, Wenjun Liu, Johnny C. Ho and co‐workers develop a rapid surface‐guided synthetic approach to introduce amorphous mixed‐metal oxyhydroxide overlayers on ultrathin Ni‐doped MnO 2 nanosheets arrays supported on a nickel foam substrate via a galvanic replacement mechanism, resulting in a monolithic electrode with greatly enhanced activity for the electrocatalytic oxygen evolution reaction in alkaline conditions.
