title: Effects of Different Carbon Matrix on the Pt0.55Co0.45 Catalysts Using for the Cathode of Proton Exchange Membrane Fuel Cell.
abstract: 20 wt% Pt0.55Co0.45/C catalysts were prepared using a chemical reduction method, with Vulcan XC-72 conducting furnace black and double-walled carbon nanotubes (DWCNTs) as the carbon supports, respectively. The catalysts were compared with commercial BASF 20 wt% Pt/C (using Vulcan XC-72 carbon as support). The materials were characterized by X-ray diffraction and transmission electron microscopy (TEM). The electrochemical performance of the Pt/C and Pt0.55Co0.45/C catalysts was evaluated by cyclic voltammetry and steady-state measurements. Electrochemical measurements indicated that the Pt0.55Co0.45 nanocatalysts exhibited improved activity in the oxygen reduction reaction (ORR) on DWCNTs compared to those on Vulcan XC-72 carbon. It is suggested that DWCNTs will provide better catalysis support than Vulcan XC-72 carbon.
