The electrochemical behavior and activity of Ag(111), Ag(110), and Ag(100) for catalyzing electroless copper deposition (ECD) baths containing 2,2'-bipyridyl were established successfully. The data provided by mixed potential analyzes showed that the deposition rates when using electrodes composed of Ag(100), Ag(110), and Ag(111) were 0.0625, 0.0696, and 0.0413 mg h~(-1)cm~(-2) respectively. Ag(110) and Ag (100) exhibited the higher catalytic effect on the activation of ECD. On the basis of Tafel analyzes, the order of catalytic strength determined for anodic formaldehyde oxidation was Ag(110) Ag(100) > Ag(111). The data from this study provide evidence that the formaldehyde oxidation governs the overall ECD reaction.
