Changes in O2 reduction activity (orr) and structural changes of carbon supported catalysts upon electrochemical stress testing are investigated. Focus is placed on two alloy catalysts of nominal Pt3Fe/C and Pt3Fe2/C compositions. Energy dispersive X-ray Spectroscopy (EDXS) spot and line analyses reveal a dependence of the Fe composition on the particle size particularly for he two as-prepared catalysts. Catalyst particles are shown to exist of a Pt enriched shell and a PtxFey alloy core. Larger (larger ca. 10 nm) particles are shown to have a higher Fe content that approaches the nominal composition suggesting that the smaller (smaller than 6 nm) Pt catalyst particles are more difficult to alloy. HAADF-STEM, XRD, and scanning electron micr...
