摘要： 以二异丙胺为模板剂,用水热法合成了磷酸硅钴铝分子筛(CoAPSO-11)纯相,测定了其化学组成。通过X射线衍射、电子探针、扫描电镜及红外光谱等对其结构进行了分析,证实Co、Si进入AlPO-11分子筛的骨架。同时对其吸附性、热稳定性、酸性和催化性能进行了研究。

Abstract: The molecular sieve CoAPSO-11, cobalt silicoaluminophosphate, and its single crystals have been prepared. The compound consists of P, Al, Co and Si with a molar ratio of 11:11:1:1. The results obtained by SEM, XPS and IR showed that parts of Al and P in frame work are substituted by Co and Si in CoAPSO-11, as compared with AlPO4-11. CoAPSO-11 has a high thermal stability and catalytic activity for isopropylbenzene cracking and methanol conversion.

Key words: cobalt silicoaluminophosphate, molecular sieve, synthesis, structure, property
