| titleOfInvention | Preparation method of nitrogen-doped double-shell structure nano catalyst |
| abstract | The invention discloses a preparation method of a nitrogen-doped double-shell structure nano catalyst, which comprises the following operation steps: (1) adding a carrier and a metal precursor into a solvent, stirring, adding a reducing agent for reduction, filtering, cleaning and drying to obtain a primary product; (2) placing the mixture in a high-temperature reaction furnace, introducing gas and calcining to obtain a nitrogen-doped nano alloy catalyst; (3) and performing dealloying treatment to obtain the nitrogen-doped double-shell structure nano catalyst. The catalyst has 5-19 times of activity of commercial 20 wt% Pt/C catalyst in oxygen reduction mass at 0.9V, has higher oxygen reduction catalytic performance, and lays a technical foundation for large-scale application of proton exchange membrane fuel cells. |
