Phosphorous-Modified Carbon Nanotube-Supported Pt Nanoparticles for Propane Dehydrogenation Reaction-中国期刊网

摘要 ThesinteringofPtnanoparticlesisoneofthemainreasonsforcatalystdeactivationduringthehigh-temperaturepropanedehydrogenation(PDH)reaction.Promotersandsupportshavebeenintroducedtoprolongthecatalystlife.However,itisstillnecessarytodevelopnovelcatalystswithrobuststability.Herein,thephosphorus-modifiedcarbonnanotube-supportedPtnanoparticleswereemployedforthePDHprocess.PhosphorusmodificationimprovesthePtdispersion,effectivelypromotingtheactivityofPt/P-CNTs.Additionally,thephosphorus-modifiedCNTscaninteractstronglywithPtnanoparticlesbyimprovingtheelectrontransferorhybridization,stabilizingPtnanoparticlesfromagglomeration,andsignificantlyenhancingthecatalyststability.
