Thin Pd membrane prepared on macroporous stainless steel tube filter by an in-situ multi-dimensional plating mechanism.
The big surface pores of a porous stainless steel (PSS) tube filter with marked roughness were jammed with aluminium hydroxide gel by a combination of ultrasonic vibration and vacuum suction, then a thin dense Pd membrane (6 microm) was plated in-situ on this pre-jammed filter by a multi-dimensional plating mechanism; after recovering the substrate pores by high temperature treatment, higher H2 permeance and complete H2 selectivity were obtained.
