用水热晶化法合成了无铝Mo-Beta沸石,讨论了合成条件对无铝Mo-Beta沸石晶化的影响,通过化学分析、XRD、IR、DTA/TGA、TEM、NMR、ICP和UV-Vis紫外漫反射光谱测定了样品的n(SiO2)/n(MoO3)比,并对其结构进行了表征,结果表明,所合成的Mo-Beta沸石晶粒均匀,Mo存在于沸石骨架中,由于Mo的掺入,引起Beta沸石红外光谱、差热分析曲线及晶胞参数,29SiMASNMR谱等发生变化。 The effects of synthesis conditions on the crystallization of aluminum-free Mo-Beta zeolite were discussed. The effects of the synthesis conditions on the crystallization of aluminum-free Mo-Beta zeolite were discussed. Vis spectroscopy was used to determine the n (SiO2) / n (MoO3) ratio of the sample. The structure of the sample was characterized. The results showed that the Mo-Beta zeolite was homogeneous and Mo was present in the zeolite framework. The incorporation of Mo causes Beta zeolite infrared spectroscopy, differential thermal analysis curve and unit cell parameters, 29SiMASNMR spectrum changes.
