| titleOfInvention | A kind of preparation method of Pt-M spherical catalyst for fuel cell |
| abstract | The invention discloses a preparation method of a Pt-M spherical catalyst for fuel cells. SiO 2 and PDDA are selected and added into pure water for dispersion and centrifugal separation, and then the separated powder is mixed with Pt (acac) 2 and a compound of metal M. Add to tetraethylene glycol and dissolve by sonication. After heating the reaction, it was centrifuged and washed with alcohol, then dried at room temperature. Finally, SiO 2 is removed to obtain Pt-M spherical catalyst. Alloy M is added to the catalyst for a fuel cell prepared by the invention, which reduces the amount of precious metals and costs, and at the same time, the spherical structure can effectively increase the specific surface area of the catalyst and has better catalytic activity. |
