多组分钒铯铜铊催化剂的表面氧性质研究

The study of surface oxygen property of VCsCuTl catalysts.

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 。

A series of catalysts were prepared by impregnation method. The TPR, O\-2\|TPD techniques were also applied to investigate the surface oxygen properties of the catalysts. The results show that Cu Tl can obviously promote the surface oxygen of the catalysts and is correlated to their catalytic properties.
