通过浸渍法制备了一系列选择氧化制取对叔丁基苯甲醛的催化剂 ,采用 O2 - TPD、TPR表征技术考察了催化剂的表面氧和晶格氧的热脱附性能以及还原性能 .实验结果表明助剂 Cu、Tl的添加对催化剂表面氧性质影响较大 ,并发现催化剂的表面氧性质与其反应性能有很好的对应关系 A series of catalysts for selective oxidation of p - tert - butylbenzaldehyde were prepared by impregnation method. The thermal desorption performance and reduction performance of oxygen and lattice oxygen of catalysts were investigated by O2 - TPD and TPR characterization techniques. The experimental results show that Additive Cu, Tl addition of oxygen on the surface of the catalyst a greater impact on the catalyst and found that the surface oxygen properties and their reaction properties have a good correspondence
