A small percentage of platinum added to silver/gold alloys that are then electrochemically dealloyed yields an extremely high surface area nanoporous metal, with pore size less than 4 mn, as shown in the figure (scale bar = 5 nm). The presence of surface platinum stabdizes the nanostructure to coarsening in air and electrolyte.
