| 抄録: | Oxygen reduction reaction (ORR) rate constants (k) on Pt and Pt-M (M = Fe, Co, Ni) electrodes were evaluated in N-ethyl-N-methylpyrrolidinium fluorohydrogenate (EMPyr(FH)1.7F) ionic liquid at 298-333K. The Pt-Fe electrode exhibited the best catalytic activity in EMPyr(FH)1.7F, because of the large surface area of its nanoporous structure after Fe dissolution. X-ray photoelectron spectroscopy and field-emission scanning electron microscopy showed that Co and Ni barely dissolved in EMPyr(FH)1.7F. The observed ORR activities of Pt-Co and Pt-Ni alloys were lower than that of Pt in EMPyr(FH)1.7F. |
