本文采用Ｐｔ与Ｃｏ比率为１∶２的摩尔比和活性炭，通过高温焙烧及通氢气还原法制成Ｐｔ－Ｃｏ／Ｃ催化剂，并将其热压在Ｎａｆｉｏｎ膜上，制成Ｐｔ－Ｃｏ／Ｃ－Ｎａｆｉｏｎ膜电极。通过稳态极化技术、Ｘ射线衍射分析（ＸＲＤ），隧道扫描电镜（ＳＴＭ）等方法，研究电极氧还原性能。结果表明，Ｐｔ与Ｃｏ通过焙烧后能形成Ｐｔ－Ｃｏ合金，且Ｐｔ－Ｃｏ／Ｃ催化剂能明显改善Ｐｔ／Ｃ催化剂的活性和稳定性，减少贵金属用量
In this paper, the Pt-Co / C catalyst was prepared by high temperature calcination and hydrogen reduction by using the molar ratio of Pt to Co as 1: 2 and activated carbon, and pressing it on Nafion membrane. Nafion membrane electrode. The oxygen reduction performance of the electrode was investigated by means of steady-state polarization, X-ray diffraction (XRD) and tunnel scanning electron microscopy (STM). The results show that Pt and Co can form Pt-Co alloy by calcination, and the activity and stability of Pt / C catalyst can be significantly improved by Pt-Co / C catalyst, and the amount of precious metal
