摘    要:用热扩散法成功地把AgI组装于NaZSM5的孔道中,对制备的样品(NaZSM5)AgI进行了化学分析、粉末XRD分析、化学吸附、红外光谱表征,研究了所制备的样品固体扩散漫反射吸收光谱及发光性质.化学分析表明,AgI已进入NaZSM5主体中.粉末XRD分析显示了组装AgI后NaZSM5沸石骨架依然存在,红外光谱表明了(NaZSM5)AgI样品骨架振动与NaZSM5的骨架振动有细微差别,这主要是由组装了AgI引起的.吸附研究说明了AgI已进入NaZSM5的孔道.固体扩散漫反射吸收光谱表明,主体NaZSM5对制备的主体客体样品光吸收几乎没有影响,(NaZSM5)AgI的吸收光谱受AgI尺寸大小的影响.发光研究表明,制备的样品能带隙很高,辐射过程很强,(NaZSM5)AgI样品系具有发光功能的复合材料.

关 键 词:NaZSM-5沸石主体  AgI客体  主客体纳米复合材料  表征

Abstract:Silver iodide nanoclusters were successfully prepared in the channels of NaZSM-5 zeolite by a thermal diffusion method. Chemical analysis, powder X-ray diffraction, nitrogen adsorption technique, and infrared spectroscopy were used to characterize the prepared samples. The solid diffuse reflectance absorption spectra and luminescence properties were studied. Chemical analysis showed that the guest silver iodide was incorporated into the host NaZSM-5. Powder X-ray diffraction analysis showed that the framework of NaZSM-5 still remained in the (NaZSM-5)-AgI samples. Infrared spectra indicate that the vibration of the framework of NaZSM-5 had little variation attributable to the encapsulation of AgI in the host. This phenomenon is due to the incorporation of silver iodide into NaZSM-5. Investigation of the absorption revealed that the guest silver iodide was encapsulated in the channels of NaZSM-5. Solid diffuse reflectance absorption spectra indicated that the absorption of prepared (NaZSM-5)-AgI host-gust samples had nothing with the host NaZSM-5. The absorption spectra of the (NaZSM-5)-AgI samples were influenced by the size of AgI nanoclusters. Luminescence investigation showed that the prepared samples had a high energy band gap and a strong radiation process. The (NaZSM-5)-AgI samples are luminescient composite materials.
Keywords:NaZSM-5 zeolite host  AgI guest  Host-guest nanocomposite material  Characterization
