Abstract
A FePtCuheterogeneous phase structure polyhedron nanoparticle, a preparing method and an application as an efficient fuel cell oxygen reduction catalyst are provided. The FePtCuheterogeneous phase structure polyhedron nanoparticle, includes: three elements of Fe, Pt and Cu; wherein the FePtCuheterogeneous phase structure polyhedron nanoparticle has a heterogeneous phase structure in which face-centered cubic and face-centered tetragonal coexist; wherein the heterogeneous phase structure is a face-centered tetragonal phase shell and face-centered cubic core with a high crystal plane index; a surface of the polyhedron nanoparticle has 1 to 2 atomic layers of enriched with Pt; a diameter distribution of the nanoparticles is at a range of 4.5 to 14.5 nm, and an average size is 8.4 nm. In the invention, hexadecylamine, iron acetylacetonate, copper acetylacetonate, platinum acetylacetonate, and 1,2-hexadecanediol are uniformly mixed, and oleylamine and oleic acid are added, condensed refluxed at 320-330° C.
