Abstract
A method for preparing a palladium-gold alloy gas separation membrane system comprising a gold-palladium alloy membrane on a porous substrate coated with an intermetallic diffusion barrier. The method includes an abrading step to increase surface roughness of the palladium to a desired range, a gold plating step with a solution of chloroauric acid (AuClH) and hydrogen peroxide, followed by annealing to produce a palladium-gold alloy membrane.
