A-type zeolite membranes were prepared onthe nonporous metal supports by using electrophoretic tech-nique. The as-synthesized membranes were characterized byXRD and SEM. The effect of the applied potential on theformation of the A-type zeolite membrane was investigated,and the formation mechanism of zeolite membrane in theelectric field was discussed. The results showed that thenegative charged zeolite particles could migrate to the anodemetal surface homogenously and rapidly under the action ofthe applied electric field, consequently formed uniform anddense membranes in short time. The applied potential hadgreat effect on the membrane formation, and more uniformand denser zeolite membranes were prepared on the non-porous metal supports with 1 V potential.
