| 英文摘要 | a ptfe/c catalyst has been synthesized by impregnation and high-temperature reduction followed by acid-leaching. x-ray diffraction, x-ray photoelectron spectroscopy and x-ray atomic near edge spectroscopy characterization reveal that pt3fe alloy formation occurs during high-temperature reduction and that unstable fe species are dissolved into acid solution. the difference in fe concentration from the core region to the surface and strong o-fe bonding may drive the outward diffusion of fe to the highly corrugated pt-skeleton, and the resulting highly dispersed surface feo (x) is stable in acidic medium, leading to the construction of a pt3fe@pt-feo (x) architecture. the as prepared ptfe/c catalyst demonstrates a higher activity and comparable durability for the oxygen reduction reaction compared with a pt/c catalyst, which might be due to the synergetic effect of surface and subsurface fe species in the ptfe/c catalyst. |
