Electrocatalytic properties of thin mesoporous platinum films synthesized utilizing potential-controlled surfactant assembly

A new method to prepare thin mesoporous platinum films by coupling potential-controlled self-assembly of surfactant-inorganic aggregates and electrodeposition processes was developed. This method uses extremely dilute surfactant solutions to generate films with accessible pores and thermally stable frameworks. Thus, the resulting films possess high surface areas that lead to enhanced electrocatalytic properties towards methanol oxidation compared to those of non-mesoporous platinum films
