ABSTRACT:
The present invention provides a molecular sieve composite membrane, which includes an anodic alumina membrane as a support and the uni-directionally oriented molecular sieve membrane grown in situ on the anodic alumina membrane. The close packing transitional metal containing aluminophosphate AFI molecular sieve crystals have successfully been grown on the anodic alumina. The molecular sieve phase bounded strongly and anchored into the anodic alumina membrane. Besides, the specific cylindrical channels of the anodic alumina membrane provides the template function to orient the growth of molecular sieves.
