Preparation of Hydrophobic Zeolite 13X@SiO₂ and their Adsorption Properties of CO₂ and H₂O

Abstract:

Zeolite 13X@SiO₂ composites have been prepared using TEOS and CTAB as the silica source and template respectively, via hydrothermal reaction. The approach of synthesizing zeolite 13X@SiO₂core-shell structures has been adopted followed by external surface modification by silane to achieve hydrophobicity. The materials were characterized by XRD, SEM, FTIR, etc. The results show that the zeolite 13X@SiO₂ core-shells structures have been prepared and their properties are maintained even after the modification. The CO₂ adsorption capacity was well maintained after silylation, however, the adsorption of water on samples was effectively inhibited by the surface modification.
