Photostimulated oxidation of water catalyzed by a tetranuclear ruthenium complex with lithium countercations

Аннотация

Photostimulated oxidation of water by potassium persulfate in the presence of photosensitizer bpy₃RuCl₂ ∙ 6H₂O and ruthenium catalyst Li₁₀[{Ru₄(μ-O)₄(μ-OH)₂(H₂O)₄} ∙ (γ-SiW₁₀O₃₆)₂] ∙ 10H₂O has been studied. It has been shown that the quantum yield of O₂ (0.29) is much higher than the quantum yield in a similar photocatalytic system with rubidium countercations (0.09).
