Beschreibung
Zusammenfassung:	The invention discloses a preparation method of a Co3O4/NiPdCo alloy/graphene composite material, which comprises: carrying out a hydrothermal reaction on palladium acetylacetonate, cobalt nitrate, nickel nitrate and 1, 2-hexadecanediol; then adding polyvinyl alcohol and ethidene diamine into a water bath, and obtaining NiPdCo alloy after hydrothermal stirring; thirdly, dissolving cobalt nitrate, adjusting the pH value, aging and calcining to obtain Co3O4; and finally, mixing the NiPdCo alloy with Co3O4 and graphene, stirring, and drying to obtain the Co3O4/NiPdCo alloy/graphene composite material. The Co3O4/NiPdCo alloy/graphene composite material prepared by the preparation method disclosed by the invention has good electrocatalytic activity, can effectively catalyze oxygen reduction reaction, and has good stability. 本发明公开了一种Co3O4/NiPdCo合金/石墨烯复合材料的制备方法，包括以下步骤：首先将乙酰丙酮钯和硝酸钴、硝酸镍以及1，2-十六烷二醇水热反应；之后水浴中加入聚乙烯醇和乙二胺，水热搅拌后得到NiPdCo合金；第三步将硝酸钴溶解后，调节pH后老化煅烧后得到Co3O4；最后将NiPdCo合金与Co3O4与石墨烯混合后搅拌，干燥后得到Co3O4/NiPdCo合金/石墨烯复合材料。本发
