Increasing durability of Pt-surface-enriched nanosize structure catalysts by multi-step platinum deposition

The sluggish reaction of oxygen reduction in proton-exchange membrane fuel cells (PEMFCs) and the durability of platinum-based catalysts have been major economical and technological barriers to the widespread application of PEMFCs. We report here on two Pt-surface-enriched nanosize structure (Pt-SEN...
