Electrocatalytic Properties of Thin Mesoporous Platinum Films Synthesized Utilizing Potential-Controlled Surfactant Assembly

A new electrochemical strategy has been developed for the production of mesoporous Pt films (see Figure). The method utilizes only a thin interfacial region of surfactant–inorganic assemblies formed on the working electrode to produce nanostructured films. The resulting films possess high surface areas that lead to enhanced electrocatalytic properties toward methanol oxidation compared to those of non‐mesoporous Pt films.
