Description

Mechano-chemical method was applied to develop a new composite catalyst consisting of tungsten carbide (WC) and platinum / carbon (Pt / C). The formation of Pt / C-WC composite particle was confirmed by TEM observation, in which we found that small Pt particles and thin carbon layer existed on the WC surface. The Pt / C-WC composite particle showed a similar catalytic activity with pristine Pt / C catalyst for hydrogen oxidation although the amount of Pt loading was about 1 / 4 of that for the Pt / C catalyst. This was confirmed in the fuel cell test as well as in the hydrogen adsorption / desorption behavior measured by cyclic voltammetry.
