New and Future Developments in Catalysis

Chapter 11. Nanoalloy Catalysts in Electrochemical Energy Conversion and Storage

... in which the catalyst was prepared by 1:1 feeding ratio of Au:Pt and was
thermally treated 250 °C in air for 30 min, which showed a particle size of 6.8 ±
1.4 nm. The data for that AuPt/C (40% wt) catalyst obtained under the condition of
a much lower dischargingcharging current density (0.04 mA/cm2electrode)
showed a discharge voltage of ∼2.7 V and a charge voltage of 3.6 V on average,
and a capacity value of 1200 mAh/gcarbon. For the Au49Pt51/C catalyst (as
shown in Figure ...
