A novel method with ethylenediaminetetraacetic acid disodium salt (EDTA-
2Na) as a stabilizing agent was developed to prepare highly dispersed Pt
nanoparticles on carbon (vulcan xc-72) to use as proton exchange membrane (PEM)
fuel cell catalysts. These nanocatalysts were obtained when the EDTA-2Na/Pt ratio
was maintained at 1:1. and the Pt/CNT catalyst exhibited large electrochemical
active surface areas, very high electrocatalytic activity. The Pt/XC-72R catalyst
with narrow size distribution was prepared by this method.
