摘    要:将水溶性壳聚糖碳化得到多孔碳材料, 然后制备了多孔碳/NiO复合材料. 透射电子显微镜(TEM), X射线衍射(XRD)和N2吸-脱附实验等结构表征显示, 材料具有富含介孔的孔道结构. 循环伏安(CV), 恒流充放电等电化学测试表明, 复合材料具有良好的电化学电容性能. 其中Ni/C质量比为2:20时, 复合材料在0.1 A·g-1电流密度下比容量可达355 F·g-1, 而且经过1500次循环比容量仍保持99%左右, 表现出良好的循环稳定性.

关 键 词:超级电容器  壳聚糖  多孔碳  氧化镍

Abstract:Porous carbons were prepared by the carbonization of water soluble chitosan and they were then used to synthesize porous C/NiO composites.Transmission electron microscopy(TEM),X-ray diffraction(XRD),and nitrogen adsorption-desorption experinents were used to characterize the structure and morphology of the products.The results showed that the mesopore-rich composites consisted of NiO crystallites and porous carbon.The electrochemical properties of the porous C/NiO composites were studied by cyclic voltammet...
Keywords:Supercapacitor  Chitosan  Porous carbon  Nickel oxide
