Abstract

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.
