Catalytic oxidation of hydrocarbons with hydrogen peroxide by vanadium-based polyoxometalates

摘要

Vanadium compounds have attracted much attention because they have widely been used for homogeneous, heterogeneous, industrial, and biological oxidation processes with alkyl hydroperoxides, H_2O_2, and O_2. The present review summarizes recent developments for homogeneous and heterogeneous liquid-phase oxidation of hydrocarbons with H2O2 catalyzed by vanadium complexes and vanadium-based polyoxometalates including our recent studies on selective oxidation of hydrocarbons with H_2O_2 catalyzed by divanadium-substituted polyoxotungstates, [γ-SiW_10O_36V_2(μ-OH)_2]~4- (Ⅰ) and [γ-PW_10O_36V_2(μ-OH)_2]~3-(Ⅱ).
