Patent ID: 8658127

Claim:
A method of preparing a mesoporous zeolite material, the method consisting of: (a) forming template-occluded primary metal-doped silicate particles having an amorphous structure by adding a solution consisting of water, silicic acid and a cationic metal component, to a heel solution consisting of water and a template stabilizer that is tetraalkylammonium hydroxide, at a temperature and for a period of time sufficient to form colloidal particles; (b) aggregating the particles of step (a) into mesoporous agglomerates via refluxing at a temperature and for a time sufficient to cause agglomeration of the particles into mesoporous agglomerates; (c) transforming the amorphous structure into a microporous nanocrystalline zeolite structure, thereby forming a mesoporous zeolitic material; and (d) removing the template of step (a) to form the mesoporous zeolite material.
