Introducing a low concentration of gold into Co(OH) 2 followed by electrodeposition of Ni(OH) 2 , yields a Co(OH) 2 ‐Au‐Ni(OH) 2 composite active in overall water splitting, as Anthony P. O'Mullane and co‐workers report in article number 1804361 . Activity for hydrogen evolution or oxygen evolution could be achieved by tuning the gold content between 0.1 and 0.2 at%. This approach may also be applicable to other metal hydroxide/metal nanomaterial composites.
