XAS of carbon supported platinum fuel cell electrocatalysts: advances towards real time investigations

The utility of XAS to provide detailed information regarding the structure of supported electrocatalysts has previously been demonstrated. A review of the literature relating to carbon supported Pt fuel cell electrocatalysts is presented. Improvements in the time resolution of the data collection wh ich have become possible with the introduction of energy dispersive monochr omators are discussed and a critical analysis of the effect of these improv ements is presented.
