One-step synthesis and chemical characterization of Pt C nanowire composites by plasma sputtering

A one-step synthesis of Pt-C nanowire composites using a plasma co-deposition method is reported. Electrodes with a Pt loading as low as 0.010 mg cm-2 are obtained. Pt particles with sizes from 1 to 2 nm are decorating with strong interactions columnar carbon nanostructures. The composite microstructure is responsible of the very high metal utilization rate as exemplified from reactions involved in fuel cell electrodes (20 kW gPt-1)
