Abstract:
1. A decal method for transferring platinum- and platinum alloy-based catalysts with nanonetwork structures, comprising steps of: (a) spraying a polymeric thin film on a substrate; (b) growing platinum- and platinum alloy-based catalysts on said polymeric thin film by the steps of: (c) processing a second heat treatment to decompose said polymeric thin film to separate said substrate and said catalysts; and (d) spraying a binder on a surface of a proton exchange membrane support to bind said support with said catalysts so as to transfer said catalysts on said support through a hot-press treatment, wherein a hydrofluoric acid solution is added and wherein the second heat treatment is operated at a temperature lower than 100 Celsius degree (° C.).
