Abstract
The invention is directed to a method for producing Palladium alloy composite membranes that are useful in applications that involve the need to separate hydrogen from a gas mixture. The method includes providing a substrate for supporting a palladium alloy film, seeding the support surface with palladium crystallites to produce an activated surface, first plating, over the activated surface, a palladium film, second plating, over the palladium film, an alloying material other than silver, and annealing the porous substrate, palladium film, and alloying material so that there is intermetallic diffusion of the alloying material into the palladium film to produce a palladium alloy film over the porous substrate.
