Abstract:
？Molybdenum-basedcatalystssupportedonAl2O3dopedwithNi,Cu,orFeoxideweresynthesizedandusedinethylbenzenedehydrogenationtoproducestyrene.Themolybdenumoxidewassupportedusinganunconventionalroutethatcombinedthepolymericprecursormethod(Pechini)andwetimpregnationoncommercialalumina.ThesampleswerecharacterizedbyX-raydiffraction(XRD),N2adsorption-desorptionisotherms,temperature-programmedreductionofH2(H2-TPR),andthermogravimetric(TG)analysis.XRDresultsshowedthattheaddedmetalswerewelldispersedonthealuminasupport.Theadditionofthemetaloxide(Ni,Cu,orFe)of2wt%bywetimpregnationdidnotaffectthetextureofthesupport.TPRresultsindicatedasynergisticeffectbetweenthedopantandmolybdenumoxide.Thecatalytictestsshowedethylbenzeneconversionof28%-53%andstyreneselectivityof94%-97%,indicatingthattheadditionofthedopantimprovedthecatalyticperformance,whichwasrelatedtotheredoxmechanism.Molybdenumoxidesplayafundamentalroleintheoxidativedehydrogenationofethylbenzenetostyrenebyitsredoxandacid-baseproperties.ThesamplecontainingCushowedanatypicalresultwithincreasingconversionduringthereaction,whichwasduetometalreduction.TheNi-containingsolidexhibitedthehighestamountofcarbondeposited,shownbyTGanalysisafterthecatalytictest,whichexplaineditslowercatalyticstabilityandselectivity.
