The electrodeposition of Pd at the interface between two immiscible electrolyte solutions has been investigated using chronoamperometric techniques, under conditions of variable applied overpotential. An alumina membrane-templated interface has been used as a means to circumvent the agglomeration phenomena shown previously to affect deposit growth at this type of interface. Palladium deposition, from aqueous solutions of tetrachloropalladate, was induced by electron transfer from an organic phase electron donor (butylferrocene). The resultant data has been interpreted in terms of classical models, previously developed for amperometric deposition on solid electrode surfaces. © 2006 Elsevier B.V. All rights reserved.
