Porous electrodes have been the center of interest in the development of devices for use in energy production, catalysis, and sensing application. By providing an enhanced surface area per unit volume, porous structures can significantly improve the kinetics and mass transfer at the interfaces of electrodes, thus enhancing the efficiency of various chemical and electrochemical reactions. Creating electrodes with ordered mesoporous structures is of special interest because it not only increases surface areas enormously but also makes it possible to study the effect of specific nanostructural details (i.e. pore sizes and pore connections) on chemical and physical properties of the electrodes. In this presentation, we present an electrochemical strategy for producing inorganic nanoporous films by utilizing self-assembly of amphiphilic molecules at solid-liquid interfaces. The spontaneous aggregation of amphiphiles at solid-liquid interfaces is a well-established phenomenon. We exploit these phenomena for inorganic synthesis by combining it with electrodeposition. When surfactants with appropriate hydrophilic groups are selected, the metal ions that need to be deposited can be strongly bound on the surface of surfactant micelles organized on a working electrode, thereby forming stable organic-inorganic interfacial aggregates. When an electrical bias is applied to initiate the deposition process, the organization of these metal ions in the interfacial assemblies directly becomes the skeleton of the inorganic deposits, resulting in ordered inorganic nanostructures. In this presentation, we will explain the principles of our electrochemical interfacial surfactant templating method in detail and discuss synthesis and characterization of several oxide and hydroxide films containing various mesoporous structures.
