中文摘要：

采用甲基三乙氧基硅烷（MTS）为添加剂,在高温（140°C）条件下水热合成出具有六方片状形貌的Y型沸石.相比于100°C左右合成的Y型沸石,高温合成的Y沸石具有更高的硅铝比值、更大的晶体宽厚比值以及对有机挥发物具有优异的吸附性能.通过X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、29Si固体核磁共振（NMR）、傅里叶变换红外（FTIR）光谱、碳氢氮元素分析（CHN）、水接触角等表征,证明了所合成的新型Y沸石具有甲基基团,它们的存在增强了疏水性能,提高了对有机挥发物的吸附能力.

英文摘要：

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.
