Electrodeposited iron-based nanofoams as precursors for transducers

Abstract

Abstract The aim of this work is the electrochemical preparation of iron-based oxide (Fe2O3, Fe3O4) nanofoams on metal substrate by accompanying hydrogen-evolution as promising precursors for transducers. Various metal substrates have been tested and the most satisfying electrolyte composition have been determined. However, various deposition parameters determine various nanofoam properties, like pore-size, density, pore-type, thickness of interconnections etc. The crystallographic composition and morphology of the electrodeposited samples have been studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively.
