FE43.4PT52.3CU4.3 HETEROGENEOUS STRUCTURAL PHASE POLYHEDRON NANOPARTICLE, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/133795
Kind Code:
A1
Abstract:
The present invention relates to a Fe43.4Pt52.3Cu4.3 heterogeneous structural phase polyhedron nanoparticle, a preparation method therefor, and an application of serving as an efficient fuel battery oxygen reduction catalyst. The heterogeneous structural phase polyhedron nanoparticle consists of Fe, Pt, and Cu and is provided with a face-centered tetragonal phase shell layer and a face-centered cubic phase nuclear structure that have a high crystal face index, 1-2 Pt-rich atomic layers are provided on the surface, and the particle diameter is 8.4 nm. The present invention is obtained by adding oleylamine and oleic acid after evenly mixing hexadecylamine, ferric acetylacetonate, copper acetylacetonate, platinum acetylacetonate, and 1,2-hexadecanediol, and performing a condensation backflow reaction under the condition of 320-330°C. The synthesized nanoparticle of the present invention has an excellent ORR property, the half-wave potential is higher by 50 mV compared with Pt/C, the quality activity is 10.9 times that of Pt/C under the half-wave potential, and the nanoparticle has the potential application value in the fields such as electro-catalysis and high density magnetic recording.
