Figure 4.

Comparison of TON, TOF, and chemical yield (CY) for RuCo₉ (blue) and CsCo₉ (red). Experiments were carried out in a KPi (40 mM) buffer at pH 7, with S₂${\text{O}}_8^{2-}$ (5 mM). [Ru(bpy)₃]²⁺ (1 mM) was added to the suspension of CsCo₉, whereas no homogeneous photosensitizer was added for the RuCo₉ catalyst.
