水溶性壳聚糖制备多孔碳/氧化镍复合材料及其电化学电容行为
Preparation of Water Soluble Chitosan-Based Porous Carbon/NiO Composites and Their Electrochemical Capacitive Behavior
摘要
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 voltammetry (CV) and galvanostatic charge/discharge measurements.We found that compared with porous carbon, the composites showed superior electrochemical capacitive performance.When the mass ratio of nickel to carbon was 2∶20, the composite had a large specific capacitance of 355 F·g-1 at a current density of 0.1A·g-1and excellent cyclability with a capacity retention of about 99％after 1500 cycles.关键词
