| 摘 要： | 随着杂原子分子筛研究领域的开拓与发展，近年来，对钛硅沸石的研究逐渐增多．Ti－ZSM－11（TS－2）型分子筛是由Reddy，Ratanasarny等1]首先合成的．钛硅沸石的表征与其它杂原子分子筛相比较为复杂，对杂原子Ti是否进入了骨架还没有一个直接的证据，且争议较多．在红外光谱的研究中，对960cm－1－980cm－1区间的特征吸收的归属也存在着很大的分歧2－4]．钛硅沸石在H2O2对有机化合物的选择氧化领域有极其优良的催化性能1]，因此，对它的开发有广泛的应用前景．本文以动态和静态相结合的水热晶化法合成了Ti－ZSM－11型分子筛．IR光…

| Abstract: | The Ti-ZSM-11 zeolite was synthesized under hydrothermal condition. All samples of Ti-ZSM-11 showed an absorption at 960cm-1 - 980cm-1 in IR spectra, and the intensity of this band decreased with the increasing of the Si/Ti ratio. The IR spectra of TS-2 was compared with that of titanate, titania, amorphous silica and gel of reactant thexture. The resultes showed that this band was also observed in amorphous silica and gel of reactant mixture, but not found in titanate and titania. This characteristic absorption in TS-2 was assigned to a strectching of a O3SiOTi] mode formed by a SiO4] tetrahedral unit bonded to a Ti(IV) ion, and the position of this band was shifted with the different coordianion circumstances of Ti atom. |
