Abstract

Methods for introducing mesoporosity into zeolitic materials are described herein that employ an acid treatment, an optional surfactant treatment, and a base treatment without filtration or purification steps between the steps. In particular, the process generally involves subjecting a zeolitic material to an acid treatment followed by a surfactant treatment and base treatment. The methods can efficiently introduce mesoporosity into various zeolitic materials, such as zeolites.
