Hydrothermal preparation of TS-1 film on cordierite with mixed templates
Titanium silicalite-1 molecular sieves (TS-1) were successfully in-situ synthesized and planted on the surface of honeycomb-shaped cordierite support by hydrothermal method. The film formed on internal wall of cordierite was characterized by BET, XRD, FT-IR and SEM. The results showed that after pretreatment with acids, cordierite supports lost their weight by 2-6％ but specific surface area increased for 5-10 times. Of them, highest specific surface area is the support pretreated by 37％ hydrochloric acid for only one time, which has superior performance in molecular sieve growth to the others. In order to get well shaped and unique crystalline of TS-1, higher ratio of TBA + /TEA + was needed. When the ratio is lower than 1.88, the TS-2 crystal could be formed and found on XRD pattern at the triplet peaks about 2 θ = 45°. Then the effects of other conditions, such as temperature, duration time, on the growth of TS-1 film were also discussed.
