| titleOfInvention | Liquid phase preparation method of platinum-based fuel cell catalyst and electrocatalysis application thereof |
| abstract | A liquid phase preparation method of a platinum-based fuel cell catalyst and an electro-catalysis application thereof relate to a nano material and a fuel cell catalyst. Adding a platinum precursor, a cobalt precursor and a catalyst carrier into a reaction container filled with an alcohol solvent, and carrying out ultrasonic homogenization in an ultrasonic instrument; adding a formaldehyde aqueous solution; sealing the reaction vessel, and starting magnetic stirring reaction; washing with a washing solution, centrifugally separating and drying; and calcining the dried product in an air atmosphere, and cooling to obtain the catalyst. The catalyst comprises platinum-cobalt nanoparticles and a catalyst carrier, wherein the platinum-cobalt nanoparticles are loaded on the catalyst carrier. The catalyst can be applied to oxygen reduction reaction of a fuel cell and a membrane electrode of a fuel cell device. The catalyst has uniform size and uniform dispersion; the process is simple and efficient; by changing reaction conditions, a plurality of platinum-based alloy catalysts with different components and sizes can be synthesized; the catalyst exhibits excellent electrocatalytic performance on both the rotating disk electrode and the fuel cell membrane electrode. |
