Cluster compounds containing Mn3SrO4 and Mn4SrO4 core structures, preparation method and application thereof

摘要

[Mn₃SrO₄] cluster compounds are synthesized in a single step from raw materials consisting of simple and inexpensive Mn²⁺, Sr²⁺ inorganic compounds and carboxylic acids by using permanganate anion as oxidant. This step can be followed by the synthesis of asymmetric biomimetic water splitting catalyst [Mn₄SrO₄] cluster compounds in the presence of water. The [Mn₄SrO₄] cluster compound can catalyze the splitting of water in the presence of an oxidant to release oxygen gas. The neutral [Mn₃SrO₄](R₁CO₂)6(R₁CO₂H)₃ cluster compound can serve as precursors for the synthesis of biomimetic water splitting catalysts, and can be utilized in the synthesis of different types of biomimetic water splitting catalysts. [Mn₄SrO₄](R₁CO₂)₈(L₁)(L₂)(L₃)(L₄) cluster compounds can serve as artificial water splitting catalysts, can be utilized on the surface of an electrode or in the catalyzed splitting of water driven by an anoxidant.
