Abstract

A layer-by-layer technique has been developed to synthesize FeOOH-Au hybrid nanorods that can be transformed into Fe2O3-Au and Fe3O4-Au hybrid nanorods via controllable annealing process. The homogenous deposition of Au nanoparticles onto the surface of FeOOH nanorods can be attributed to the strong electrostatic attraction between metal ions and polyelectrolyte-modified FeOOH nanorods. The annealing atmosphere controls the phase transformation from FeOOH-Au to Fe3O4-Au and alpha-Fe2O3-Au. Moreover, the magnetic and optical properties of as-synthesized Fe2O3-Au and Fe3O4-Au hybrid nanorods have been investigated.
