摘要
Abstract
The attapulgite coated with nitrogen-doped carbon was prepared by high temperature heat treatment of the attapulgite coated with polyaniline, which was synthesized by in-situ chemical polymerization of aniline. The morphology and chemical structure of the samples were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), conversion analysis for differential thermal analysis (DTA). The electrochemical performances of the composites as the electrode materials for supercapacitors were investigated by cyclic voltammetry, gslvsnostantic changing-discharging and electrochemical impedance spectroscopy. The results show that the attapulgite coated with nitrogen-doped carbon from polyaniline has a good capacitance performance in 6 mol·L–1 aqueous KOH solution, its specific capacitance can reach 161.9 F·g–1 at the scan rate of 20 mV·s–1 and it also exhibits a low inter resisitance and a good stability of the temperature coefficient of capacitance.关键词
