Iridium Oxide-Polymer Nanocomposite Electrode Materials for Water Oxidation.
Nanocomposite anode materials for H2O oxidn. have been readily synthesized by electrodeposition of Ir oxide nanoparticles into poly(pyrrole-alkylammonium) films, previously deposited onto C electrodes by oxidative electropolymn. of a pyrrole-alkylammonium monomer. The nanocomposite films were characterized by electrochem., TEM, and at. force microscopy. They showed an efficient electrocatalytic activity toward the O evolution reaction. Data from Tafel plots demonstrated that the catalytic activity of the Ir oxide nanoparticles is maintained following their inclusion in the polymer matrix. Bulk electrolysis of H2O at C foam modified electrodes showed that the Ir oxide-polymer composite presents a higher catalytic activity and a better operational stability than regular oxide films.
