Protons preferred : A cobalt catalyst is reported that evolves H 2 electro‐ and photocatalytically at room temperature, in pH‐neutral water, and in the presence of atmospheric O 2 (see scheme). The catalyst shows respectable Faradaic efficiencies under N 2 and 21 % O 2 in N 2 , and can be used under both homogeneous and heterogeneous conditions.
