采用浸渍法制备了Pd/C、Pt/C、Ni/CNT和Pd/CNT催化剂，并用BET、XRD等手段对催化剂进行了表征。TEM和H-2化学吸附。在硝基环己烷加氢制环己酮肟反应中对这些催化剂进行了测试。结果表明，在0.2MPa、323 K的温和条件下，5% Pd/CNT催化剂的硝基环己烷转化率为97.6%，环己酮肟选择性为85.9%。产品包括环己酮肟、环己胺、环己醇和N-环己基羟胺。结果表明，较高的反应温度有利于环己胺的生成，而环己醇的生成量随反应温度的升高而减少。(C)2011 Elsevier B. V.保留所有权利。
The Pd/C, Pt/C, Ni/CNT and Pd/CNT catalysts were prepared by impregnation method and characterized by BET, XRD. TEM and H-2 chemisorption. These catalysts were tested in the hydrogenation of nitrocyclohexane to cyclohexanone oxime. The results show that 5% Pd/CNT catalyst exhibits good performance, it gives nitrocyclohexane conversion of 97.6% and cyclohexanone oxime selectivity of 85.9% under mild conditions of 0.2 MPa and 323 K. The products include cyclohexanone oxime, cyclohexylamine, cyclohexanol and N-cyclohexylhydroxylamine. It has been found that higher temperature is in favor of the formation of cyclohexylamine, while the amount of cyclohexanol decreases with the increment of reaction temperature.
