用红外(IR)、固态核磁共振(SS-NMR)顺磁共振(ESR)、漫反射(Diffuse Reflectance)、光电子能谱(ESCA)、紫外可见光(UV-VIS)等现代谱仪研究了HY沸石分子筛的表面酸性及在Y型分子筛上[Ni(Ⅲ)(en~*)_2Cl_2]~+配合物的合成和特性表征。证明了以P(CH_3)_3为探针分子,用IR和SS-NMR研究分子筛的表面酸性,灵敏度高,能区别酸的类型,对在分子筛上合成过渡金属配合物的研究将有利于了解多相催化的反应机理。但为了证实在分子筛上金属配合物的生成和它的性能表征,必须藉助于现代谱仪的帮助。各种现代谱仪在多相催化的研究中足非常有用的工具,并起着越来越重要的作用。
HY zeolite has been studied by modern spectrometers such as infrared (IR), solid state nuclear magnetic resonance (SSR), diffuse reflectance, photoelectron spectroscopy (ESCA) and UV-VIS SURFACE ACIDITY OF ZEOLITE AND ITS SYNTHESIS AND CHARACTERIZATION OF [Ni (Ⅲ) (en ~) _2Cl_2] ~ + COMPLEX ON Y - TYPE ZEOLITE. It is proved that P (CH_3) _3 can be used as probe molecule to study the surface acidity of molecular sieve by IR and SS-NMR. The sensitivity is high, and the type of acid can be distinguished. The study on the synthesis of transition metal complexes on molecular sieve will help to understand more Phase catalytic reaction mechanism. However, in order to confirm the formation of metal complexes on molecular sieves and their characterization, it is necessary to rely on the help of modern spectrometers. A variety of modern spectrometers are useful tools in heterogeneous catalysis and play an increasingly important role.
