通过等体积浸渍法制备了催化剂Pt/TiO₂。利用间甲基苯酚及其中间产物（甲基环己酮、甲基环己醇、甲基环己烷和甲苯等）在催化剂Pt/TiO₂上的反应探究了甲基苯酚加氢脱氧的反应路径。利用XRD、H₂-TPR、TEM、NH₃-TPD、XPS等对催化剂的表面性质和结构性质进行了表征。结果表明，金属Pt能高度分散在载体TiO₂上。Pt/TiO₂催化间甲基苯酚加氢脱氧反应主要存在2种路径：一种是间甲基苯酚直接脱氧生成甲苯（DDO路径）；另一种是间甲基苯酚先加氢生成甲基环己酮、甲基环己醇，然后脱水生成甲基环己烯，再加氢生成甲基环己烷。

Pt/TiO₂ catalyst is prepared by incipient wetness impregnation.In order to get the reaction pathways of m-cresol hydrodeoxygenation,m-cresol and its intermediate products such as methyl cyclohexanone,methyl cyclohexanol,methyl cyclohexane and toluene are investigated over Pt/TiO₂ catalyst at 250^oC and ambient hydrogen pressure.The structures and properties of Pt/TiO₂ is also investigated by various techniques such as XRD,TEM,BET,XPS,CO chemisorption,NH₃-TPD,H₂-TPR etc.It is found that Pt particles disperse highly onto the TiO₂ supporter.There are two main reaction pathways for hydrodeoxygenation of m-cresol.The first one is the direct deoxygenation to toluene (DDO path) and the second one is that hydrodeoxygenation of m-cresol forms firstly methylcyclohexanone and methylcyclohexanol over Pt,then these two intermediates perform rapidly dehydration to gain methylcyclohexene that is again hydrogenated to methylcyclohexane.Among these two pathways,DDO path is predominant.
