摘要
对近年来具有高活性、高选择性的TiO_2负载单金属和双金属催化剂(钛载催化剂)在同时含有C=C和N=O或C=O键的不饱和化合物的液相选择性加氢中的应用进行了述评;探讨了选择性加氢的机理和催化剂制备涉及的因素(如制备方法、温度、TiO_2载体晶型和活性组分等)对催化性能的影响;对如何制备工业上适用于液相选择性加氢反应的钛载催化剂提出了建议。
Research advances in the titania-supported monometallic and bimetallic catalysts, which exhibited high catalytic activity and selectivity in liquid-phase selective hydrogenations of the reactants containing C=C and N=O or C=O simultaneously, were summarized in this paper. Mechanisms of the selective hydrogenations and influences of the preparation factors on the catalytic properties, such as preparation methods, temperature, titania crystal phases and active components, were discussed. Some opinions on how to prepare titania-supported catalysts used in the industrial liquid-phase selective hydrogenation were proposed.
