| 摘 要： | 利用透射电子显微技术（TEM）、X射线能谱技术（EDX）以及电子能量损失谱技术（EELS）对Ti原子是否进入到TS-1钛硅分子筛骨架进行了研究。结果表明，TS-1钛硅分子筛中存在的微量TiO2粒子的EELS信号中O-K边与Ti-L2边的能量差为70eV左右；而钛硅分子筛(TS)粒子的EELS信号中O-K边与TiL2边的能量差为79eV左右。对比TiO2、TS粒子的EELS，发现TS粒子的TiL2、Ti-L3边与TiO2粒子的TiL2、TiL3边的能量差为1eV，这种能量差异可以作为Ti原子进入TS-1钛硅分子筛骨架的一种证明。

| Abstract: | The transmission electron microscopy(TEM), X-ray energy dispersive spectroscopy(EDX) and electron energy loss spectroscopy(EELS) were used to analyze if the Ti atoms engaged into the framework of titanium silicalites zeolite(TS-1). The results showed that the difference between O-K and Ti-L2 was about 70 eV for TiO2, while it was about 79 eV for TS particles. Compared the EELS of TiO2 with that of TS particles, it was found that the difference between Ti-L2 and Ti-L3 in TiO2 and TS particles was 1 eV, which could be a proof for Ti atoms engaging into the framework of TS-1. |
