摘要：

Zeolite composite membranes have been attracting great interests due to their important potential applications in separation and catalysis. Many techniques[1] have been involved in the preparation of zeolite composite membranes. However, it is still challenged to obtain a defect-free zeolite composite membrane with high permeability. Approach of seeding and second growth was proved effective to form a homogeneous and continuos membrane[2]. This paper presents some preliminary results in our lab on the synthesis of A-type zeolite composite membrane via forming seeding layer on alumina ceramic and subsequently converting seeds to zeolite crystals composing membrane.
