摘要
采用静电纺丝的方法制备了钴镍比分别为2∶1、1∶1、1∶2的镍钴金属氧化物碳纳米纤维复合材料,通过XRD表征了3种复合材料的晶体结构、材料形貌,并通过SEM和能谱图分析了其组分,最后对材料进行了析氧反应电化学性能的研究。结果表明:钴镍比为2∶1时得到的复合材料作为析氧阳极催化剂的催化活性及稳定性最好。
Cobalt-nickel metal oxide carbon nanofiber composite materials(ratios of cobalt to nickel 2∶1,1∶1 and 1∶2)were prepared by electrostatic spinning method.XRD was used to characterize the crystal structure of the three kinds of composites,SEM and EDS were used to analyze the morphology and composition of the materials,and the electrochemical performance of the oxygen evolution reaction of these materials was studied.The results showed that the composite with a cobalt-nickel ratio of 2∶1 had the best catalytic activity and stability for oxygen evolution as anode catalyst.
