Abstract: The invention provides methods of recovering a pore-forming agent from an inorganic material that defines a plurality of mesopores having a controlled cross sectional area to form a mesostructure having long-range crystallinity and also to methods of making one or more mesostructures that features removal, recovery, and/or reuse of the pore-forming agent. Suitable pore-forming agents include, for example, surfactants.
