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
