- 中文摘要: 以硼、矽或金屬元素如鐵、鈷、鎂、錳、鋅等分別加入 (方程式無法摘錄) -5鋁磷分子篩結構中修飾其物理及化學性質。所得到的矽鋁磷及金屬鋁磷分子篩的結晶構造相似而熱穩定性,酸性及間二甲苯反應觸媒活性大不相同,其性質依所含的金屬,硼或矽不同。同時以各種光譜方法來證實矽或金屬存在於分子篩的骨架結構中。
- 英文摘要: The properties of crystalline microporous molecular sieve (方程式無法登錄) have been modified by incorpora-ting B,Si,Fe, Co, Mg, Mn or Zn element into its framework. The crystal structure of (方程式無法登錄) has not beendisrupted, but the thermal stability, acidity and catalytic activity on m-xylene conversion of these materi-als result in a remarkable diversity. The framework siting of the elements in (方程式無法登錄) and (方程式無法登錄) is alsostudied by various spectroscopic methods.
