Nanowires are nanostructures with a diameter in the nanometer range, and in contrast with nanorods, they have an unlimited length, so that this may extend into the µm range. Oxide nanowires are produced in IMO-IMOMEC by means of chemical synthesis routes including hydrothermal growth (e.g. ZnO) or AAO template based routes combined for instance with aqueous solution-gel precursors . These oxide nanowires show promise for a range of nanotechnological applications, including sensor arrays, hybrid photovoltaics, nanoelectronics, photocatalysts, supercapacitors etc. In all these applications the increased surface to volume ratio plays a crucial role in order to improve the material’s performance.
