| 摘 要： | 以VO2+为自旋探针,观察了VO2+负载的分子筛载体的微环境,在计算机上模拟了复杂的多中心的实验ESR谱,发现VO2+在载体上的分散状况不仅取决于制备条件,也和分子筛的种类有关。利用这种方法,可得探针在载体上所处微环境的信息,进而可用于指导配位聚合催化剂载体的选择。

| Abstract: | Using VO2+ as spin probe, the micro-environment of VO2+ supported on zeolite was observed by ESR technique. Computer program was built for simulating ESR spectra with complicated and multi-centers. It was found that the dispersion character of VO2+ is dependent upon the preparation conditions employed and the carriers chosen. This may serve as a new method to get micro-environment information of carriers and can be used in the choice of carriers of coordination catalysts. |
