Abstract
A quantity of solution sufficient to dissolve a pH controlling substance and/or substantially dissolve a surfactant without substantial excess solution is controlled under a set of time and temperature conditions to transform an inorganic material having long-range crystallinity to a mesostructure having long-range crystallinity. The method employs concentrated conditions that have a consistency similar to a thick slurry. The economic viability of scaling up such thick slurry methods is improved relative to prior more dilute methods of transforming an inorganic material to a mesostructure.
Claims21
A method of making a mesostructure comprising:
- exposing an inorganic material having long-range crystallinity to a solution comprising a pH controlling substance and a surfactant under time and temperature conditions sufficient to define, in said inorganic material, a plurality of mesopores having a controlled cross sectional area forming a mesostructure having long-range crystallinity, wherein the quantity of said solution is in the range of from about 0 volume percent to about 20 volume percent in excess of the amount sufficient to dissolve said pH controlling substance and substantially dissolve said surfactant, wherein said inorganic material is selected from the group consisting of metal oxides, zeolites, zeotypes, aluminophosphates, gallophosphates, zincophosphates, titanophosphates, and mixtures of two or more thereof.
