Hierarchically assembled 1-dimensional hetero-nanostructures: Single crystalline RuO₂ nanowires on electrospun IrO₂ nanofibres

We report a facile growth route to synthesize hierarchically grown single crystalline metallic RuO₂ nanowires on electrospun IrO₂ nanofibres via a combination of a simple vapour phase transport process with an electrospinning process. This synthetic strategy could be extended to design a variety of highly branched network architectures of functional hetero-nanostructures with possible future applications.
