Abstract

The primary subject of the invention is an iron oxide/hydroxide-containing conducting polymer composite, which comprises a) a conducting polymer, and b) an iron oxide/hydroxide compound incorporated in the conducting polymer wherein the composite contains iron oxide/hydroxide compound other than magnetite, and the conducting polymer is different from polyaniline (PANI). The further subject of the invention is the process for the electrochemical production of the above-mentioned conducting polymer composite by one of the following processes: Process I, which comprises the following steps: a) providing a conducting polymer layer; b) electrochemical reduction of the conducting polymer layer; c) contacting the reduced conducting polymer layer with an aqueous solution of ferrate ions; d) optionally repeating steps b) and c); e) optionally separating and drying the obtained composite; or Process II, which comprises the following steps: a) providing a conducting polymer layer; b) contacting the conducting polymer layer with an aqueous solution of ferrate ions; c) electrochemical oxidation of the conducting polymer layer in an aqueous solution of ferrate ions; d) electrochemical reduction of the oxidized conducting polymer layer in an aqueous solution of ferrate ions; e) optionally repeating steps c) and d); e) optionally separating and drying the obtained composite.
