Abstract
The invention is directed to a simple method for preparing highly dispersed, highly loaded platinum metal elements on various carbon substrates, including conductive carbon black, which is utilized in fuel cell electrodes. Utilizing carbon with a controlled point of zero charge (PZC) and maintaining a desired pH value throughout the adsorption of metal onto the carbon substrate, a high metal loading is achieved for a given surface area of the carbon substrate.
