Abstract
In this work recent progress on a novel preparation route for iridium-based electrodes applied in PEM-electrolysis cells is communicated. Substoichiometric titanium oxide (TiO2-x) particles have been synthesized to prepare a nano porous coating on top of a titanium electrode substrate. The TiO2-x-material is stabilized on the substrate by laser sintering and utilized as an electrically conductive support for iridium catalyst particles, which were deposited via electrochemical methods. The influence of the deposition current density and iridium concentration in the electrolyte were analyzed, resulting in samples with increased catalytic activity when compared to reference samples in linear sweep voltammetry.
