Abstract
Pt nanoparticles supported on Vulcan
XC-72R, synthesized by a surfactant-stabilized colloidal
method, exhibited excellent properties as anode
catalyst for low-temperature fuel cell. The Pt/C
catalyst prepared with binary-surfactant (Brij
35 + Tween 20) at 10 times CMC had an average
particle size of 2.8 nm with quite a narrow distribution
between 2 and 4 nm. Our preparation method
resulted in complete reduction of Pt and full loading
of Pt nanoparticles on the carbon. The home-made Pt/
C catalyst showed higher EAS and better catalytic
activity than a commercial Pt/C catalyst. The method
used in this study provided an easy and reproducible
procedure for the preparation of Pt nanoparticles
supported on carbon.
