摘要
通过静电纺丝和溶剂热的方法合成了一维NiCo2O4复合中空纳米纤维,利用扫描电子显微镜,X射线衍射,利用电化学工作站进行析氧,电容性质的分析,对一维NiCo2O4复合中空碳纳米纤维的形貌,结构,性质进行了测试与表征.结果显示,合成的一维NiCo2O4复合中空纳米碳纤维与使用同样比例溶剂和合成温度的刺球状的NiCo204颗粒具有更好的析氧性质,循环稳定性和更好的电容性质以及更大的活性表面积.而且经过多次循环之后,一维NiCo2O4复合中空纳米碳纤维的电催化活性并没有明显的减弱,说明这种以多孔碳纤维为基底通过水热的方法合成出来的复合材料具有一定的实际应用价值.
One-dimensional NiCo204 composite nanofibers were synthesized by electrospinning and solvothermal methods.Scanning point brain microscopy and X一ray diffraction were used to analyze oxygen and electrochemical properties.The morphology,structure and properties of the one-dimensional NiCo2 O4 composite nanofibers were tested and characterized.The results show that the synthesized one一dimensional NiCo2 O4 composite nanofibers have better oxygen evolution electrocatalytic properties,cycle stability,better capacitance properties and larger active electrochemical surface area,as well as the thorn一shaped nano-NiCo2 O4 using the same ratio of solvent and synthesis temperature.Moreover,after repeated cycles,the electrocatalytic properties of the one-dimensional NiCo204 composite nanofibers were not significantly weakened,which indicats that the composite material synthesized by hydrothermal method with porous carbon fiber as the substrate has certain Practical application value.
