Abstract

Metal doping carbon aerogels are prepared via polymerization of glutaraldehyde and chitosan with Ni(NO3)2 and Co(NO3)2 doping under freeze - drying method. The as - prepared product are carbonized at 900 °C in a nitrogen atmosphere. The obtained doping carbon aerogels were characterized by means of N2 - adsorption, X-ray diffraction (XRD), cyclic voltammetry, galvanostatic charge–discharge measurements and electrochemical impedance spectroscopy (EIS). The analysis results shows that doping carbon aerogels exhibit a high specific surface area, up to 387 m2/g, and a high specific capacitance, up to 105 F/g at a current density of 1.0 A.g-1. In a nutshell, this work provides a new method to prepare carbon aerogels with high specific surface area and specific capacitance.
