High aspect ratio nanoscale multifunctional materials derived from hollow carbon nanofiber by polymer insertion and metal decorationElectronic supplementary information (ESI) available: Experimental details. See DOI: 10.1039/c0cc00571a

A novel high aspect ratio material which can simultaneously display multiple functions such as proton and electron conductivity and electrocatalytic activity has been developed by incorporating both platinum nanoparticles and phosphoric acid doped polybenzimidazole along the inner and outer surfaces of a hollow carbon nanofiber. A multifunctional material which simultaneously displays proton and electron conductivity along with electrocatalytic activity has been developed by a novel strategy.
