Abstract

A novel synthesis strategy is presented for depositing metallic Ag at the anode during simultaneous electrochemical oxidation of Al. This unexpected result is achieved based on galvanic coupling. Metallic dendritic nanostructures well-anchored in a high surface area supporting matrix are envisioned to open up a new avenue of applications.

Keywords: anodic aluminum oxide; anodic oxidation; galvanic coupling; nanodendritic silver; transmission electron microscopy.
