Zusammenfassung:
In this study, we describe the electroless synthesis of lepidocrocite
(gamma-FeOOH) nanotubes produced in ion track etched polycarbonate
foils. The foils act as templates after they had been irradiated with
heavy ions to produce latent tracks that were etched with a desired
diameter. Templates are used to fabricate shape formed 1D nanostructures
in general. The synthesis of lepidocrocite nanotubes was carried out in
a simple two-step method: firstly, particles were formed by
precipitation in aqueous solution; secondly, nanotubes were produced by
the deposition of the particles inside the nanochannels of the
polycarbonate template. Solvent effects were considered to achieve
homogeneous growth resulting in well-defined nanotubes of constant wall
thickness along the tube axis. Lepidocrocite nanotubes were
characterized by scanning electron microscopy (SEM), energy-dispersive
X-ray (EDX), Raman, and Mossbauer spectroscopy. (C) 2011 Elsevier B.V.
