摘要： Zn2Al layered double hydroxide pillared with Dawson polyoxometalates, P2W17ZO618-(Z=Mn2+, Co 2+, Ni2+, Cu2+, Zn2+) was prepared. A basal space of ca. 16 nm indicates the intercalated Dawson ions to be oriented with their C2 axis perpendicular to the double hydroxide layers(with the exception of P2W17Zn-LDH). The IR and13P MASNMR spectral reveal that the Dawson ions retain their integrity in the interlayer space of LDH. A preliminary study shows that these compounds are highly active catalysts for the oxidation of cyclohexene with molecular oxygen.
