Abstract
The application of cyclic voltammetry to the evaluation of the platinum content of carbon-supported platinum catalysts was investigated. The results were compared to those obtained by INAA and FAAS. A good linear relationship between the hydrogen deposition charge and platinum loading in the catalyst was found for platinum of different particle size. This method has the advantage of being readily available in many laboratories in addition to providing the real surface area of the metal at the same time.
