基于聚多巴胺的氮掺杂碳材料的制备及其电化学性能
Preparation and Electrochemical Performance of Nitrogen Doped Carbon Materials Based on Polydopamine
摘要
Abstract
Porous carbon materials have been extensively studied in the field of electrode materials for supercapacitor due to their high surface area,excellent electron conductivity and good chemical stability.The composition and pore structure of carbon materials directly affect their electrochemical performance.In order to further improve their capacitance performance,nitrogen doped carbon materials with excellent electrochemical performance were prepared for the first time by high temperature carbonization with polydopamine as precursor and KOH as activator.The surface morphology, structure and composition of the obtained N-doped porous carbon materials were characterized by scanning electron microscopy(SEM),transmission electron microscopy (TEM), X-ray diffraction spectra(XRD), Fourier transform infrared spectrometer(FT-IR), X-ray photoelectron spectroscopy(XPS)and Raman spectroscopy, respectively.The electrochemical performances were investigated by cyclic voltammetry and galvanostatic charge/discharge in 6 mol/L KOH electrolyte.The results show that the specific capacitance of the material can reach 269 F/g at the current density of 1 A/g due to the synergistic effect of double layer capacitance and pseudocapacitance, and the capacitance still remains 93.5%after 1000 charge-discharge cycles.关键词
