Abstract
A method for preparing titanium-containing molecular sieves include the following steps: irradiating a mixed solution containing a silicon source, a template and a titanium source by a light source containing ultraviolet light before crystallization, and then subjecting the mixed solution to crystallization and post-treatment to obtain the titanium-containing molecular sieve. In the method for preparing titanium-containing molecular sieve of the present invention, the mixed solution containing the silicon source, the template and the titanium source is treated with the ultraviolet light, and free radicals generated by the ultraviolet light can effectively dissociate titanium oligomers and accelerate the hydrolysis of the silicon source, and thus match the hydrolysis rate of a silicon-titanium precursor, thereby preventing a titanium monomer from self-polymerization to form non-framework titanium. Therefore, a titanium-containing molecular sieve that does not contain the non-framework titanium can be quickly prepared.
