摘要

Keggin-type heteropolymolybdates have been found to catalyze the selective oxidation of isobutane with molecular oxygen. The preferable contents of Cs and V are 2.5 and 1, respectively, and the addition of Ni enhanced the catalytic activity for the oxidation of isobutane. The presence of steam did not affected the catalytic performance very much. Cs_(2.5)Ni_(0.08)H_(1.34)PVMo_(11)O_(40) also catalyzed the oxidation of propane and ethane. It was suggested by IR, XRD, and ~(31)P NMR data that the Keggin structure was maintained during the oxidation.
