    摘要: The present invention relates to a synthesis method for ETS-10 titanosilicate molecular sieves. The method comprises the steps of mixing a titanium oxide hydrosol, a silicon source, a sodium hydroxide, a fluorine-containing mineralizer and a water to give a gel and adjusting the pH thereof to 10.4 to 10.8; and hydrothermal crystallizing the gel at 170 to 250° C. for 10 to 100 hours to obtain the ETS-10 titanosilicate molecular sieves. In the synthesis method for ETS-10 titanosilicate molecular sieves provided by the present invention, a titanium oxide hydrosol is used as the titanium source to synthesize the ETS-10 titanosilicate molecular sieves, and the problem that conventional soluble titanium salt-based titanium sources tend to hydrolyze and the problem of poor dispersibility for the titanium source system of insoluble titanium oxide are therefore prevented. The ETS-10 titanosilicate molecular sieves synthesized has high purity and high crystallinity.
