氮掺杂石墨烯柔性薄膜的制备及其超电容性能
Preparation and Supercapacitor Performance of a Flexible Nitrogen-doped Graphene Film
摘要
Abstract
ABSTRACT:Objective To improve the electrochemical performance of graphene films for supercapacitors. Methods Flexible ni-trogen-doped graphene ( N-doped graphene) films with porous structure were synthesized by hydrothermal and pyrolysis methods. The structure of the N-doped graphene films were analyzed by scanning electron microscope ( SEM) , X-ray diffraction ( XRD) and isotherms. The electrochemical capacitance of N-doped graphene films was examined by three-electrode system test cyclic voltam-metry and galvanostatic charge-discharge methods. Results The experiments indicated that the flexible N-doped graphene films re-tained the folded and transparent characteristics of graphene oxide, and formed a three-dimensional porous structure as well. The surface area of N-doped grapheme was measured to be 280. 78 m2/g by the nitrogen adsorption-desorption test. The specific dis-charge capacitance for the material was 169 F/g in 1. 0 mol/L NaSO4 solution when the current density was 0. 1 A/g. Conclusion The doping of nitrogen atoms and the porous structure of the flexible N-doped graphene films could effectively improve the superca-pacitor performance of the graphene material.关键词
