Disclosed is a method for preparing a TS-1 molecular sieve with hierarchical pores, wherein a silicon-titanium ester polymer is used as a titanium-silicon source to obtain the TS-1 molecular sieve with hierarchical pores. In the preparation method, silicon and titanium are connected evenly to the same polymer, and the hydrolysis rates thereof upon hydrolyzation are comparable, which can prevent the precipitation of TiO |
