Abstract

Pd alloys with non-noble transition metals are of interest for various catalytic applications. The electrodeposition of Pd-Zn alloy was investigated from an ammonia citrate electrolyte at neutral pH in this report. Cyclic voltammetry, galvanostatic deposition, and potentiostatic stripping were used to understand the electrochemical behavior of the system. Films were characterized with electron microscopy, X-ray diffraction, Raman spectroscopy and X-ray photoelectron spectroscopy. While Zn-rich alloy films with various compositions were electrodeposited at different current densities, a porous but stable tetragonal PdZn bimetallic compound was obtained after anodic stripping.
