  • Any suitable solution can be used for dispersion of the nanowires and then subsequent refiuxing.
  • Exemplary solutions include organic solvents such as ethylene glycol, as well as alcohols and aqueous-based solutions.
  • the catalyst supports of the present invention provide for increased catalytic activity relative to other catalysts/catalyst supports without the disclosed characteristics, the amount of catalyst particles that are required for a particular application can be reduced, thereby allowing for a reduced material cost and thus reduced cost for fuel cell production. In addition, utilizing less catalyst in the electrodes allows for the production of thinner electrodes, and thus reduced resistance of the electrodes.
