摘要
鉴于氢是一种清洁高效能源,燃料电池成为未来动力能源的首选之一。但是阻碍其商业化的主要瓶颈在于燃料电池用催化剂的成本。Pd Fe/C双金属催化剂具有高活性和稳定性,并且能有效地降低催化剂的成本。采用透射电子显微镜(TEM)、X射线衍射法(XRD)和循环伏安法(CV)等方法对催化剂进行表征。电催化性能测试结果表明Pd Fe/C(n(Pd):n(Fe)=2:1)的电流密度是Pd/C的6.6倍。
Fuel cells represent an attractive technology for tomorrow＇s energy vector because hydrogen is an efficient fuel and environmentally clean, but one of the important challenges for fuel cell commercialization is the preparation of active, robust and low-cost catalysts. The synthesis and processing of Pd Fe/C catalysts, as described in this report, serves as an intriguing way to address this challenge. The Pd Fe/C is characterized by an array of analytical techniques including transmission electron microscopy, X-ray diffraction. The electrochemical tests（cyclic voltammerty（CV）） showed that the activity of Pd Fe/C（n（Pd）：n（Fe）=2：1） is about 6.6 times of Pd/C for formic acid electrooxidation.
