Patent ID: 7985400

Claim:
A method for making a mesoporous or combined mesoporous/microporous inorganic oxide comprising the steps of: a) combining a mixture consisting of a nonaqueous source of an inorganic oxide with an organic complexing and pore-forming ag b) reacting the source of inorganic oxide with the complexing and pore-forming agent at a complexation temperature to provide at least one water soluble complex which is thereafter dissolved in water to provide an aqueous mixture, wherein said source of inorganic oxide is an inorganic compound and wherein the complexation temperature ranges from about 150° C. to about 250° C., and wherein a preformed microporous zeolite is added to the aqueous mixture; c) decomposing the at least one complex to provide a porous material precursor having a mesoporous inorganic oxide framework containing at least some organic pore-forming agent with the microporous zeolite embedded in said mesoporous inorganic oxide framework; and d) removing at least a major portion of the organic pore-forming agent from the inorganic oxide framework by solvent extraction and/or calcination to provide a mesoporous or mesoporous/microporous inorganic oxide characterized by an X-ray diffraction pattern having at least one peak at 0.3 to 3.5 degrees in 2 θ.
