Abstract
The corrosion rate of palladium is measured as a function of potential in . A typical corrosion rate is for an electrode with a roughness factor of 1.6. Passivation of the palladium dissolution occurs and is monitored by collection of Pd(II) at the ring electrode. Soluble palladium is produced simultaneously with the reduction of an oxidized electrode. This soluble palladium is separated into two categories. One category is associated with the reduction of surface palladium oxide while the other is associated with the reduction of phase oxide. Dissolution processes cause significant roughening of the electrode surface at .Keywords
