PdNi/C catalysts have been successfully synthesized by the
simultaneous reduction method using NaBH4 as a reductant and
have been characterized by different physicochemical methods.
XRD analyses confirm the formation of face-centered cubic crystalline
Pd and Ni(OH)2 on the carbon powder for the PdNi/C
catalysts.The TEM images show the well-dispersed metal particles
on the carbon powder,and EDS data indicate a uniform distribution
of composition.The CV and CP results demonstrate that the
Pd2Ni3/C catalyst exhibits superior activity and stability toward
EOR in alkaline media compared with the Pd/C catalyst,and the various
oxidation states of Ni,which are uniformly distributed around
Pd,account for the role of Ni as a catalytically enhancing agent
toward EOR in alkaline media.Fuel cell performance tests demonstrate
that the optimized Pd2Ni3/C catalyst prepared in this work
is a promising anode catalyst for alkaline DEFCs by giving higher

现在通过同步还原方法,用NaBH4做还原剂,已成功合成了PdNi/C催化剂,这些催化剂的特点在于它们具备多种不同的物理化学性质.经过X射线衍射（XRD）分析,确认在PdNi/C催化剂的碳粉上形成了面心立方晶体钯和氢氧化镍晶体.透射电子显微镜（TEM）观察到的图像显示碳粉上存在着分布均匀的金属微粒,而且电子数据系统（EDS）的数据也表明合成物分布均匀.循环伏安法（CV）和化学纯度法（CP）的测试结果表明：与Pd/C催化剂相比,Pd2Ni3/C催化剂对碱性介质中的催化剂运行末期（EOR）展示出优异的活动性和稳定性,而且在钯周围均匀分布着不同氧化态镍,这说明镍在碱性介质EOR方面扮演着加强催化反应的媒介角色.燃料电池性能测试表明：这项工作所准备的最优化Pd2Ni3/C催化剂是适用于碱性直接乙醇燃料电池（DEFC）的一种有发展前景的阳极催化剂.
