Phase Transformation during the Selective Dissolution of a CuPd Alloy: Nucleation Kinetics and Contribution to Electrocatalytic Activity.

This study determined the critical parameters for the morphological development of the electrode surface (the critical potential and the critical charge) during anodic selective dissolution of a Cu-Pd alloy with a volume concentration of 15 at.% palladium. When the critical values were exceeded, a phase transition occurred with the formation of palladium's own phase.
