Top: Oxygen evolution with successive additions of oxidant S2O82- (5 mM) to a KPi (40 mM) buffered suspension of RuCo9 (10 mg, 0.9 μmol) at pH 7. Bottom: Oxygen evolution after addition of photosensitizer [Ru(bpy)3]2+ (1 mM) and oxidant S2O82- (5 mM) as solid reagents to a KPi (40 mM) buffered suspension of recycled RuCo9 at pH 7 compared with the same experiments starting from fresh CsCo9.
