Claim Text:
1. A method for preparing a substrate surface structured with thermally stable metal alloy nanoparticles comprising providing a micellar solution of amphiphilic molecules in a suitable solvent; loading the micelles of said micellar solution with metal ions of a first metal salt; loading the micelles of said micellar solution with metal ions of at least one second metal salt; depositing the metal ion-loaded micellar solution onto a substrate surface to form a film comprising an ordered array of domains; co-reducing the metal ions contained in the deposited domains of the film by use of a plasma treatment, wherein the gas plasma is selected from the group consisting of pure hydrogen and a mixture of hydrogen and inert gas to form an ordered array of nanoparticles comprising an alloy of the metals used for loading the micelles on the substrate surface wherein the first metal is a noble metal, and the at least one second metal is a member selected from the group consisting of noble metals and transition metals, and wherein a molar ratio of the first metal to the at least one second metal is in a range from 9:1 to 1:9.
