Abstract
Abstract
Iron (III) oxide nanowires were grown by direct thermal oxidation of iron coupons or plates. The synthesized Fe2O2 (hematite) nanowires were then placed in a tube furnace at a specified distance (3 to 3.5 inches) from the ZnO/carbon source powders. When the source materials were heated to high temperatures Zn and ZnO molecules evaporated and moved to the low temperature region, where the Fe2O2 (hematite) nanowires were located, and condensated onto the Fe2O2 (hematite) nanowires to form a coating layer. The thickness of the coating layer can be controlled by changing the coating time. The morphology of the final nanocomposites was examined by high resolution scanning electron microscopy techniques. Such nanocomposites may have potential applications in drug delivery, sensing and solar cells.
