Specific features of the formation, catalytic activity, and corrosion stability of PdCu electrolytic co-deposit
A mixed electrolytic deposit (ED) of PdCu (~20 at.% Cu) is synthesized from a solution of 1 mМ PdSO 4 + 5 mМ CuSO 4 + 0.5 M H 2 SO 4 in the region of copper underpotential deposition (+400 mV vs. RHE). The incorporation of copper into the Pd deposit increases its true surface area ( S true ) by a...
