NiOP/GO薄膜制备及其电化学性质研究

Preparation and Electrochemical Properties of Graphene Oxide/Electrodeposited Nickel Oxide Thin Film

采用电化学沉积法制备镍氧化物纳米粒子(NiOP)/石墨烯氧化物(GO)/玻碳(GC)薄膜,在活性碳纤维上沉积石墨烯氧化物和氧化镍,并通过扫描电镜、循环伏安、交流阻抗等方法对该薄膜进行表征。结果表明,该方法制备的NiOP/GO/GC薄膜比NiOP/GC和GO/GC膜具有较小的电阻、较好的电子转移特性和较高的电化学电容性质,分析原因是由于GO和NiOP协同作用的结果,说明其作为制作超级电容器的电极材料具有广阔前景。

Nickel oxide nanoparticles （ NiOP）/graphite oxide （ GO ）/glassy carbon （ GC ） thin film was prepared by the electrodeposition, depositing graphene oxide and nickel oxide on the activated carbon fibers, and characterized by scanning electron microscopy （SEM）, cyclic vohammetry （CV） and electrochemical impedance spectroscopy （EIS）. The results showed that the NiOP/GO/GC films prepared by this method had smaller resistance, better electron transfer properties and higher electrochemical capacitance than the NiOP/GC and GO/GC films. The reason may be due to synergistic effect of GO and NiOP, indicated that it can be used to make the supercapacitor electrode material.
