Resumen

Binary oxides of IrOx:RuOy were synthesized and characterized as electrocatalysts for the oxygen evolution reaction. The catalysts were prepared by using a colloidal method in aqueous solution and a subsequent thermal treatment. The physical characterization was carried out by X-ray diffraction (XRD) and the lattice parameters, unit cell volumes (V) and the crystal lattice distortion ratio were calculated. Half cell electrochemical evaluation of binary oxides was carried out in an inert diamond electrode (BDD, A=1cm2) substrate, in order to achieve reproducibility and a stability measurements in a potential range of 0 to 2 V vs. NHE. Half Cell chronoamperometric studies by 24 h show a IrOx:RuOy 20:80 with the highest stability, and a current density of 146 mA cm-2 at 1.44 V vs. NHE. Finally the binary oxide was evaluated in a single electrolysis cell at different operation temperatures obtaining 1.28 A cm-2 at 1.8 V (80 °C).
