Conclusion
• The hydrogen adsorption/desorption experiments reveal that
the synthesized nanoporous PtIr electrodes possess
extraordinarily high active surface area.
• The further electrochemical studies show that the presence
of Ir dramatically improves the electrocatlytic activity of Pt
toward the electrochemical oxidation of CO and methanol
and the electrochemical reduction of oxygen.
• Among the four synthesized nanoporous PtIr electrodes,
Pt85Ir15, Pt72Ir28, Pt60Ir40, and Pt50Ir50, the nanoporous
Pt60Ir40 electrode exhibits the largest electroactive surface
area, the lowest charge-transfer resistance, and the highest
electrochemical activity.
