摘要

Abstract

Iron nanoparticles were uniformly deposited on glassy carbon electrode by electrochemical cyclic voltammetry，and the Fe core/Pt shell nanoparticles were further obtained through “galvanic replacement”.SEM observation illustrated that the cuboid nanoparticles dispersing uniformly on GC surface.The electrocatalytical properties for ethanol oxidation of the nano-Pt/GC，nano-FePt/GC were studied by cyclic voltammetry（CV）.The nano-FePt/GC electrode shows high electrocatalytical activity.The catalytic activity is in the order of：nano-Pt/GC＜nano-FePt/GC.The onset potential（Ei）of ethanol oxidation on nano-FePt/GC electrode is negatively shifted 0.044 V，and the steady oxidation current density（jp）is enhanced about 2.16 times，compared with nano-Pt/GC electrode.
