A Cu(OH) 2 @CoCO 3 (OH) 2 · n H 2 O (CCHH) core–shell heterostructure nanowire array acts as robust 3D oxygen evolution reaction catalyst. It needs an overpotential of 270 mV to drive 50 mA cm −2 in 1.0 m KOH, outperforming CCHH nanowire arrays on copper foam and most reported Co‐based oxygen evolution reaction catalysts in alkaline media. It is also efficient for methanol electrooxidation.
