| titleOfInvention | Pt or Au modified porous PdFe intermetallic compound and preparation method and application thereof |
| abstract | The invention discloses a Pt or Au modified porous PdFe intermetallic compound and a preparation method and application thereof, belonging to the technical field of electrochemistry. The intermetallic compound is a nano particle, the inner core of the nano particle is an ordered PdFe intermetallic compound, the surface of the nano particle is a porous structure with Pd uniformly distributed, and the surface of the porous structure is modified with Pt or Au. The preparation method comprises the steps of using palladium acetate and ferric salt as metal sources, loading the metal sources on a carbon carrier, thermally decomposing acetate in a protective atmosphere to obtain a loaded PdFe intermetallic compound, etching Fe on the surface, and preparing the Pt or Au modified PdFe intermetallic compound with porous surface and ordered kernel by adopting a surface modification technology. The Pt or Au modified porous PdFe intermetallic compound prepared by the invention has higher activity and stability when being used as a cathode oxygen reduction reaction catalyst and an anode hydrogen oxidation reaction catalyst of a fuel cell. |
