Photoinduced Oxidation of Water with Potassium Persulfate in the Presence of Ruthenium Trinuclear Complex

详细

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.
