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.
