Abstract

Dense Pd-Ag/MPSS composite membranes were fabricated on macroporous stainless steel substrate (MPSS) by novel surfactant induced electroless plating (SIEP) process. SIEP was effective in synthesizing dense and thinner Pd-Ag films on MPSS with shorter deposition time in presence of cationic DTAB. SIEP membranes showed 3–8 times higher H2 permeance compared to that of conventional EP membranes. The SEM, XRD, and EDS studies confirmed the formation of Pd-Ag alloy and no diffusion of MPSS substrate metal components into the Pd-Ag film. The Pd-Ag membrane (15 μm thickness) was tested for long-term stability under thermal cycling (623–723-623 K) up to 42 days.
