Templated Materials: Bottom‐up Generation of Miniaturized Coaxial Double Electrodes with Tunable Porosity (Adv. Mater. Interfaces 12/2015)

Two electrodes in one are obtained based on a bottom‐up approach leading to a fully integrated microelectrochemical cell with independently addressable coaxial electrodes, as described by A. Kuhn and co‐workers in article 1500192. The inherent macroporosity ensures tunable high surface areas for both cylindrical electrodes, thus allowing efficient transport and conversion of electroactive molecules. Such coaxial architectures are desirable for miniaturized electrochemical devices such as (bio)fuel cells, supercapacitors or biosensors.
