Photoinduced Oxidation of Water with Potassium Persulfate in the Presence of Ruthenium Trinuclear Complex
The kinetics and mechanism of the photoinduced reaction of water oxidation with potassium persulfate in the presence of the tris(bipyridyl) complex bpy3RuCl2 ∙ 6H2O as a photosensitizer and the trinuclear ruthenium complex (NH3)5Ru–O–Ru(NH3)4–O–Ru(NH3)5Cl6 have been studied. It has been shown that this complex is converted to a more active water oxidation catalyst when four or five NH3 ligands are replaced by oxygen atoms.
