Abstract

Thin Palladiun/SiO2 composite membrane supported on porous stainless steel has been fabricated by a novel preparation procedure. SiO2 colloid suspensions with different particle sizes were applied to modify the pore size of the substrate and also form an intermediate SiO2 layer to support the palladium layer. Palladium nuclei were seeded by a chemical vapor deposition process using Pd(F6acac)2 as metal precursor, and then a palladium layer thinner than 10 μm was prepared by electroless plating. The membrane had a hydrogen permeance of 2.7×10−6 mol/m2.s.Pa and a permselectivity of PH2 / PN2 in the range of 300–400 at 773K. The preparation process showed that SiO2 layer had a unique property for palladium adhesion compared with other studied metal oxides. The seeding process by chemical vapor deposition showed this step is significant for the preparation of a defect-free membrane. A novel electroless plating process was also applied using a weak acidic both, which is different from the usually used basic ones containing N2H4. The surface morphology and component of the membrane have been studied by scanning electron micrograph (SEM) and energy-dispersive X-ray analysis (EDX). The permeance and permselectivity of the membrane to hydrogen have bean measured at different temperatures.
