　　TheDraftofAcademicPresentation

　　国际会议的口头报告模板，每页ppt你需要讲什么东西需要分页详细写，尽量口语化，如下是本人参加比利时会议的模板，供大家参考。

　　开场白

　　Iamsohonoredtobewithyoutocommunicateacademicquestionsandideas.

　　Thetileofmyacademicpresentationis“Thepreparationandcatalyticperformanceofporoussilicananotubefunctionedwithheteroatoms”

　　Ishallonlytaketenminutesofyourtime.

　　Iwilltalkaboutthetopiconthepreparationofporousmaterials.

　　Firstofall,iwannaintroducemyself.Icomefromnanjinguniversityoftechnology,nanjingcity,china.

　　Allourresearchesareconductedbytheacademicthoughts.Generallyspeaking,wearecommittedtoporousmaterials.Inordertoexplorehigh-performancefunctionalizedmaterialsforPilotexperimentsandscale-upproduction;wetunethestructure,suchascompositionandmorphologystepbystepandoptimizethemfurther.What’smore,thepossiblesynthesismechanismsarealsoinvestigated.Today,thepresentationisbasedontheright-handbranch.

　　Itisknownthatmesoporoussilicahaveexcellentcharactersasthecatalystcarrier,suchas……..

　　Butduetolackofactivesites,wehavetointroduceorganicorinorganicspeciesasactivesites.Andthecatalyticperformanceneedtobefurtherimproved.

　　Asweknow,thethreefactorsincludingactivity,scaleanddiffusionfactorplaydecisiveroleinthecatalysis,affectingtheyield,selectivity,stabilitystrongly.Inourpresentation,wemainlyfocusontheinfluenceofscalefactoronthecatalysis.

　　P7

　　Duetolackofactivesitesformesoporoussilica,twomainmethods（surfaceloading,modifiedframework）arewidelyreported,bywhichvariousorganicorinorganicactivesitescanbeimmobilizedonthesurfaceorincorporatedintotheframeworkofmesopooussilica.

　　P8

　　Thoughvariousmorphologiesofmesoporossilicawerewidelysynthesized,thesynthesisofthemesoporossilica,withthreesimultaneouscharacteristicsincludingdopedmetal,mesoporousstructureandspecificmorphology,isalwaysachallenge,whichisrarelyreported.

　　Inotherwords,forourcaseexploringapropercondition,atwhichthesiliconandmetalsourcescansimultaneouslyhydrolyze,canensureadesiredmaterial.

　　Next,let’slookatthesyntheticsteps.Firstly,….Then,….Afterthat,….Atlast,weobtainedthe

　　Inthiswork,bychangingthesynthesisconditions,suchas…,andsoon,thepuremesoporoussilicawithdifferentmorphologiesweresynthesized,includingnanosphere,nanorod,helix,capsuleandnanotube.Wewillfocusonthepreparationandcatalyticapplicationofmesoporoussilicawithnanotubemorphology.学术会议英文演讲模板
