A Combined Rotating Disk Electrode/X-ray Diffraction Study of Co Dissolution from Pt 1-x Co x Alloys

The oxygen reduction activity of a series of Pt1-xCox catalysts (with high Co content) sputter-deposited onto 3M's nano-structured thin film support was measured with Rotating Disk electrode techniques. The activity was found to be much higher than that measured on Pt only. It was however not s...

Zusammenfassung:	The oxygen reduction activity of a series of Pt1-xCox catalysts (with high Co content) sputter-deposited onto 3M's nano-structured thin film support was measured with Rotating Disk electrode techniques. The activity was found to be much higher than that measured on Pt only. It was however not stable with repeated potential cycling. Ex-situ x-ray diffraction measurements of the disks during testing showed loss of bulk Pt from the lattice.
