Abstract: Titanium silicalite-1 molecular sieve (TS-1) was in situ synthesized on the surface of honeycomb-shaped cordierite support by a hydrothermal method. XRD, FT-IR and SEM were used to characterize the samples. The optimal process of preparing TS-1/cordierite including synthesized from cheaper preplursor was studied. Meanwhile, the effects of crystallization period and molar ratio of H2O and SiO2 in their mother solution on the growth of TS-1 on monolithic cordierite support were also researched experimentally. The results show that a coating of TS-1 crystals grows successfully on the surface of monolithic cordierite support pretreated with 37% hydrochloric acid for 6h, and the weight of the cordierite is increased by 10%--16%.

Key words: monolithic cordierite support, titanium silicalite-1 molecular sieve, in-situ synthesis
