Abstract

Needle-like crystals of ruthenium-molybdenum polyoxometalate having a composition of Na₄(NH₄)[RuMo₇O₂₅]•8H₂O (RuMo7) were synthesized with high reproducibility. With cetylpyridinium cation, RuMo7 was modified and its catalytic features were evaluated using oxidation of cyclohexanol to cyclohexanone with t -butyl hydroperoxide or hydrogenperoxide (H₂O₂). The results indicated that RuMo7 exhibits high rate for the former reaction and that RuMo7 has high potential for H₂O₂ decomposition.
