| titleOfInvention | A kind of low platinum high performance catalyst for fuel cell and preparation method thereof |
| abstract | The invention belongs to the technical field of fuel cells, in particular to a low-platinum high-performance catalyst for fuel cells and a preparation method thereof. In the method, ZIF-67 formed by coordinating a cobalt precursor with 2-methylimidazole is used to mix and stir with XC-72 dispersed in methanol solution to carry out surface modification, and the surface-modified XC-72 is subjected to carbonization treatment , and then use ethylene glycol to reduce chloroplatinic acid to carry platinum, and finally obtain a low-platinum high-performance catalyst for fuel cells. In the present invention, the surface-modified XC-72 has a larger specific surface area, so it can generate more active sites, and at the same time, non-precious metal Co atoms are introduced to form a PtCo alloy, and the electrochemical performance of the catalyst is improved. Therefore, the prepared catalyst material has the advantages of low platinum content, large specific surface area, good stability, excellent electrochemical activity, good electrical conductivity, etc., and is suitable for popularization and application in the field of electrochemical catalysis. |
