Abstract
Capturing volatile organic compounds (VOCs) under humid conditions using zeolites suffers from the dramatically decreasing adsorption capability with relative humidity (RH) increase. Herein, a surface-induced polymer coating method is proposed to design hydrophobic zeolite. The as-synthesized novel hydrophobic Y zeolite@hypercrosslinked polymer composite (Y@P) is demonstrated with excellent adsorption capability for VOCs. In particular, the toluene adsorption capacity of Y@P-2-80 composite is two times higher than that of Y zeolite, and the Qwet/Qdry values are 97.2% at 90 %RH, indicating that the toluene adsorption capability of Y@P-2-80 is almost unaffected by vapor. The proposed surface-induced polymer coating method provides a promising and universal strategy for effective VOCs capture under wet conditions using zeolites with enhanced hydrophobicity.
