摘要
Compositions and methods for introducing mesoporosity into zeolitic materials employing sequential acid, surfactant, and base treatments are disclosed herein. Mesopores can be introduced into zeolitic materials, such as zeolites, by treatment with an acid and surfactant followed by treatment with a base. The resulting mesoporous zeolitic materials can have a total 20 to 135 Å diameter mesopore volume of at least 0.05 cc/g. Additionally, the resulting mesoporous zeolitic materials can have a total 0 to 20 Å micropore volume of at least 0.10 cc/g.
