Comparison of the light-driven oxygen evolution data catalyzed by RuCo₉ and by Co₃O₄ under the same reaction conditions^a,b.

Catalyst	TON	TOF (h−1)	CY (%)
RuCo9	3.2	2.3	17.2
Co3O4	0.9	0.3	12.8

^aTON, total turnover number at the final reaction time; TOF, slope of the oxygen evolution curve at the starting time; CY, total chemical yield at the final reaction time.

^bThe experiments were performed in a KP_i (40 mM) buffer at pH 7 with [Ru(bpy)₃]²⁺ (1 mM) as photosensitizer, S₂${\text{O}}_8^{2-}$ (5 mM) as sacrificial electron acceptor, and with 13.99 μmols of Co in the form of RuCo₉ or Co₃O₄.
