Abstract
Methods for enhancing the mesoporosity of a zeolite-containing material. Such methods may comprise contacting a composite shaped article containing at least one zeolite and at least one non-zeolitic material with at least one pH controlling agent and at least one surfactant. Such methods may be performed under conditions sufficient to increase the pore volume of at least one 10 angstrom subset of mesoporosity.
