摘要
ThecatalyticperformanceofCs-substitutedphosphomolybdicsaltswasstudiedforselectiveoxidationofisobutane.Theresultsofactivitytestsrevealedthat360°Cwastheoptimalreactiontemperature.Itwasdemonstratedthatoxidizingsitesnotonlytookdominatingpartintheactivationofisobutane,butalsoinfluencedtheproductdistribution.Besides,appropriateCsadditionledtomoderateacidityofcatalysts,favoringtheselectivitytodesiredproducts.Furthermore,toobtainpartiallyreducedcatalysts,differentcalcinationatmosphereswereinvestigatedandcertainproportionofMo~(5+)producedduringcalcinationwascrucialfortheredoxreaction.ThecatalystcalcinedinN_2showedthehighestyieldofMAA(7.0%).Fe-substitutionenhancedtheactivityofcatalystsbyrapidreoxidationofMo~(5+).
