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.
