  • Electrocatalytic activity and anodic stability of electrodeposited ruthenium-rhodium coatings on titanium
    Vuković, M... ...
    The stabilizing effect of rhodium addition to ruthenium coatings on titanium under anodic polarization in acidis solutions is described. The addition of rhodium to the coating leads to both an ... overall improved stability of the electrode, and an increase of the electrochemically active surface area. The service-life of a Rh-Ru coating polarized at 0.12 A cm$^-2$ in 0.5 mol dm$^-3$ sulphuric acid is improved by at least two orders of magnitude, while deterioration of the electroactive surface area never exceeds 30 %. The rotating ring-disc electrode measurements show the dissolution of the coating at potentials above the onset of the oxygen evolution reaction at 1.1 V versus SCE.
