The effect of electroless plating time on the morphology, alloy formation and H2 transport properties of Pd-Ag composite membranes

► The effect of short plating times on the morphology of Pd-Ag deposits was studied. ► Using short electroless depositions, the Pd/Ag alloy was formed at 500 °C. ► The contribution of the diffusion-solution mechanism was isolated. ► An accurate estimation of Sievert's transport parameters was performed.
