Description
Summary:A new procedure to prepare ultrathin membrane composed of nanoparticles was investigated. The nanoparticles were prepared in aqueous solution containing PdII ions by sonochemical reduction. Electrophoresis was used to fix the nanoparticles on a porous substrate disc. The ultrathin membrane was successfully prepared with the combination procedure, and the obtained Pd membrane showed high perm-selectivity for H2 and 3.85 of the separation factor of H2/N2 at room temperature.
