Effects of Hydrophobic Species on the Oxygen Reduction Reaction on the High-Index Planes of Pt3Fe

Pt3Fe(111), Pt3Fe(775) = 7(111)–(111), and Pt3Fe(544) 9(111)–(100) electrodes show the highest activity in low-index planes, n(111)–(111), n(111)–(100) series of Pt3Fe, respectively. The surfaces these were modified with hydrophobic species such as THA+, melamine, ionic liquid ([MTBD][beti]), effects on oxygen reduction reaction (ORR) studied. All improved ORR all examined. Pt3Fe(111) 0.1 M HClO4 containing μM melamine was 2.1 times higher than that without giving 39 bare Pt(111). durability examined melamine-containing solution.
