摘要
以碳纳米管(CNT)为催化剂载体,以RuCl3.nH2O活性组分前驱物,采用浸渍法制备了无定形水合RuO2/CNTs催化剂。苯甲醇、环己醇等醇类作为研究对象,考察了RuO2纳米催化剂的催化活性,试验表明:该催化剂可在温和的条件下,以较高的催化氧化活性将苯甲醇、环己醇等醇类转化为相应的醛或酮,并考察了不同载体对负载RuO2催化活性的影响,碳纳米管作为载体的催化剂表现出较高的催化活性。采用XRD,TEM以及XPS等分析方法对催化剂进行表征。
Carbon nanotubes supported RuO_2 catalyst was prepared by incipient wetness impregnation method using RuCl_3·nH_2O as precursor. The activity and selectivity of RuO_2/CNTs catalyst for oxidation of benzyl alcohol,cyclohexanol and other alcohols were evaluated.The results indicated under mild conditions benzyl alcohol,cyclohexanol and other alcohols were oxidized with high activity and selectivity,yielding corresponding aldehyde or ketone.Meanwhile,the effect of different supports on catalytic activity was investigated.Carbon nanotubes supported catalyst exhibits the highest catalytic activity. RuO_2/CNTs nanocatalyst was characterized by XRD,TEM and XPS.
