摘要：

In this study, the ordered mesoporous structure (HMS) was used as the carrier for Ge catalyst to enhance the catalyst stability. The results show that the large specific surface area of HMS material can efficiently improve the dispersion of Ge species and inhibit the catalyst deactivation caused by coke deposition. It is found that the Ge species can be embedded into the framework of HMS, which can effectively weaken the reduction, agglomeration and loss of the active Ge species. Under the joint action of these positive factors, both dehydrogenation activity and catalyst stability of 10Ge/HMS catalyst have been effectively improved.
