Abstract [en]

One-dimensional iridium and iridium oxide fibers were prepared by electrospinning of polyvinyl pyrrolidone ethanol solution which contained iridium(III) acetylacetonate as iridium precursor. The Ir precursors/polymer composite fibers were subsequently thermally annealed at 500 degrees C in air for 4 hours to remove the organic parts and leave IrO2 fibers. Metallic iridium fibers were obtained by reducing the IrO2 fibers with hydrogen. Also tubes by fiber templates-process is used to demonstrate how metallic Ir, IrO2 and Pt nanotubes can be produced by combining atomic layer deposition and electrospinning.
