TiO nanotube (TNT) supported Rh and Ru nanoparticle catalysts were prepared impregnation-photoreducing procedure and characterized with various methods. Their catalytic performances in hydroformylation were evaluated by using vinyl acetate and cyclohexene as substrates. The results indicate that the presence of Ru in the catalysts can enhance the catalytic activity of catalysts for the hydroformylation of vinyl acetate, but do not play the same role in the hydroformylation of cyclohexene; the sequence of loading metal has a significant effect on the catalytic performances of the title catalysts. Additionally, it is found that Ru/TNTs shows catalytic activity for the hydroformylation of vinyl acetate though it does not for the hydroformylation of cyclohexene.
通过浸渍-光还原法制备了TiO纳米管（TNT）负载的Rh和Ru纳米颗粒催化剂，并用多种方法对其进行了表征。以醋酸乙烯酯和环己烯为底物，评价了它们在氢甲酰化反应中的催化性能。结果表明，催化剂中Ru的存在可以提高催化剂对醋酸乙烯酯氢甲酰化反应的催化活性，但对环己烯氢甲酰化反应没有同样的作用；负载金属的顺序对标题催化剂的催化性能有显著影响。此外，发现Ru/TNTs对醋酸乙烯酯的氢甲酰化反应具有催化活性，尽管它对环己烯的氢甲酰化反应没有催化活性。
