Abstract:

We hydrothermally synthesized sheet-like crystals of zeolite Y at high temperature (140 °C) using methyltriethoxysilane (MTS) as an additivity. Compared with the zeolite Y synthesized at 100 °C, the zeolite Y synthesized at high temperature has a high Si/Al ratio, a large crystalline width/thickness ratio and has good adsorption for organic volatile compounds. Characterization by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), 29Si nuclear magnetic resonance (NMR), Fourier transform infrared (FTIR) spectroscopy, elemental analysis and water contact angle measurements suggests that the zeolite Y synthesized at high temperature contains methyl groups, which can be responsible for the improvement in sample hydrophobicity and adsorption capacity.

Key words: Zeolite Y, High-temperature, Sheet-like morphology, Adsorption, Organosilane
