摘要：
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@SiO2 core-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. © (2014) Trans Tech Publications, Switzerland.
