Adsorption is one of the most effective methods to control the concentration of VOCs pollution. In this work, the hierarchical USY zeolites with size-controlled mesopores are obtained via NH4HF2-etching and surfactanttemplating process. It is found that the non-framework aluminum inside USY is effectively removed by NH4HF2-etching, and the irregular mesopores inside NH4HF2-etched USY are transformed into small-sized mesopores with a size of-4 nm after subsequent surfactant-templating treatment. The formation mechanism of the small mesopores with controllable pore size is elucidated, and the adsorption properties of NH4HF2-etched USY-s for different VOCs molecules are demonstrated.
