【摘要】 以吡咯为单体、FeCl₃为氧化剂,通过低温水热法制备出球形聚吡咯（PPy）,然后将PPy在N₂保护下直接炭化获得球形富氮炭材料（SC）.借助X射线衍射（XRD）、扫描电镜（SEM）、红外光谱（FTIR）、元素分析及N₂吸附-脱附对产物进行了表征.电化学测试结果显示,SC电极在6.0mol/L KOH的电解液中、-0.9～0.1V的电势范围内具有良好的电容行为,比电容高达235F/g.更多还原

【Abstract】 A spherical polypyrrole was synthesized using as pyrrole monomer and FeCl₃ as oxidant via a low temperature hydrothermal method,and then the polypyrrole was directly carbonized to prepare a spherical nitrogen-enriched carbon material（SC）at the atmosphere of N₂.The samples were characterized by X-ray （XRD）,scan electron microscopy（SEM）,FT-IR spectrometer（FT-IR）,element analysis and N₂ adsorption -desorption.The electrochemical measurement revealed the SC electrode exhibited good capacitance behavior in 6.0 mol/L KOH aqueous electrolyte from-0.9 to 0.1 V,and its specific capacitance reached as high as 235 F/g.更多还原
