The synthesis of titanium silicalite by two methods (gas-solid isomorphous substitution of Ti4+ for Si4+ and hydrothermal crystallization synthesis), aiming at decreasing its cost, and the characterization of the prepared catalyst are presented. In the hydrothermal crystallization synthesis method of titanium silicalite-1 (TS-1), TPABr can be used to replace TPAOH and the amount of TPABr can be decreased to 0.05 (TPA(+)/SiO2). Organic amine cannot act as a template in the presence of TPA(+). It can only regulate the basicity of the gel. The order of the template effect of different templates is as follows: TPA(+)>TBA(+)>TEA>>organic amine. In the preparation of titanium-containing zeolite by secondary synthesis, the nature of the precursor and the preparation conditions have great influence on the incorporation of titanium into the framework. The mechanism of gas-solid isomorphous substitution is proposed, and under its guidance, we have successfully prepared Ti-ZSM-5, Ti-ZSM-11, Ti-beta, and Ti-mordenite. The synthesized titanium-containing zeolites have been evaluated through catalytic hydroxylation of phenol, oxidation of styrene and epoxidation of propylene with aqueous H2O2 Results show that the Ti-containing zeolites possess high activity both in hydroxylation, styrene oxidation and in epoxidation.
