Bi-functional catalytic materials, denoted as MITSn, are synthesized by supporting precious metal on hollow titanium silicalite, and become new modified titanium silicalites with hollow structure and precious metal being combined. The samples have been characterized by various instruments, their catalytic performances in the propylene direct epoxidation are also investigated. The results have indicated that the special modification treatment not only can introduce Pd into MTSn, but also can make the stable combination of precious metal with titanosilicate, and the hollow structure in MTSn, can be convenient for molecular diffusions.
