Abstract

The Keggin-type di-iron-substituted γ-SiW10{Fe(OH2)}2O38 6- showed high efficiency of hydrogen peroxide utilization for the oxidation of cyclohexane. The efficiency and catalytic activity greatly depended on the structures of the iron centers. Such a structure dependency of the catalysis is significant and the remarkable catalytic performance of di-iron-substituted polyoxometalate may be related to the catalysis by methane monooxygenase. Not only cyclohexane but also cyclooctane, n-hexane, n-pentane, and adamantane were catalytically oxygenated with high efficiency of hydrogen peroxide utilization. Even methane and ethane were oxidized. It was also demonstrated that the potassium salt of γ-SiW10{Fe(OH2)}2O38 6- oxidized methane in water.
