| titleOfInvention | Fuel cell cathode catalyst and preparation method and application thereof |
| abstract | The invention relates to a fuel cell cathode catalyst and a preparation method and application thereof, wherein 2-amino-terephthalic acid and iron salt are used as raw materials, a solvothermal synthesis method is adopted to prepare a metallic iron-organic framework material, the metallic iron-organic framework material is washed for three times by using N, N-dimethylformamide and then filtered, the filtered precipitate is dried to obtain a precursor, the precursor is roasted at 550-650 ℃ in an inert gas atmosphere, and then acid treatment is carried out to obtain a nitrogen-iron doped carbon nano material, wherein the solvent adopted by the solvothermal synthesis method is an N, N-dimethylformamide organic solvent. The nitrogen-iron doped carbon nano material prepared by the preparation method has excellent oxygen reduction catalytic activity, better initial potential and limiting current and stable methanol resistance, and the electron transfer number of the nitrogen-iron doped carbon nano material is close to that of a four-electron transfer way. |
