以柠檬酸钠为络合剂,在乙二醇体系中采用有机溶胶法制备出了PdCo/C催化剂,XRD研究结果表明催化剂具有面心立方结构,粒度小,分散性好,同时元素钴的加入使催化剂的Pd-Pd间距缩小。采用电化学方法评价了催化剂对于氧气还原反应的活性,结果表明:PdCo/C催化剂具有比Pd/C要好的氧还原活性,同时具有Pt/C催化剂无法比拟的抗甲醇中毒能力。 PdCo / C catalyst was prepared by organic sol method in the ethylene glycol system using sodium citrate as complexing agent. The results of XRD indicated that the catalyst has a face-centered cubic structure with small particle size and good dispersibility. At the same time, addition of elemental cobalt Pd-Pd catalyst to narrow the pitch. The results showed that the PdCo / C catalyst has better oxygen reduction activity than Pd / C, and has the anti-methanol poisoning ability unmatched by Pt / C catalyst.
