Effect of pre-annealing temperature on the growth of aligned α-Fe2o3 nanowires via a two-step thermal oxidation

Pre-annealing as part of a two-step thermal oxidation process has a significant effect on the growth of hematite (α-Fe2O3) nanowires on Fe foil. High-density aligned nanowires were obtained on iron foils pre-annealed at 300°C under a dry air flow for 30min. The X-ray diffraction (XRD) patterns indi...
