摘要

A novel Pd/silicalite-1 composite membrane supported on the macroporous tubular stainless steel substrate was successfully fabricated by electroless plating at 303 K. The structure, morphology and gaseous permeability of the membrane were detected by X-ray diffractiometry (XRD), scanning electron microscopy (SEM) and single-gas permeation test, respectively. Results confirm the formation of a thin,smooth, and continuous Pd/silicalite-1 composite membrane. The obtained composite membrane at 773 K, at 0.1 MPa pressure drop, suggesting the potential application for H2 separation.
