Catching the sunlight : The disordered Co 1.28 Mn 1.71 O 4 was synthesized by a facile reduction method in the presence of amorphous MnO 2 precursors and Co 2+ . It exhibits relatively high hydrogen‐production activity under visible‐light irradiation (see figure). The larger number of active sites in the bulk catalyst endow nanoparticles with improved water‐reduction activity. This is the first demonstration of disordered ternary oxides for visible‐light‐driven hydrogen evolution in the absence of a cocatalyst.
