ABSTRACT:
The invention relates to a method for producing metal oxide fibers with diameters on the micro- and nanometric scale by using electrospinning. At least one polymer is dissolved in a solvent, a metal salt is dissolved in this polymer solution, and this mixture is subsequently electrospun into fibers. Breaking down the polymer renders metal oxide fibers accessible that can be optionally reduced into the corresponding metal fibers.
