【摘要】 聚吡咯（PPy）导电性能好；钴硫化物的理论比电容高，但导电性较差。将PPy与钴硫化物复合，可得到性能较好的电化学储能材料。设计并合成在管状PPy（PPy-NTs）表面原位生长Co₃S₄的复合电极材料PPy/Co₃S₄,研究反应温度和时间对电化学电容的影响。在160℃下反应6 h得到的PPy/Co₃S₄,在0.5 mol/L H₂SO₄溶液中以100 mV/s的速率扫描[0.69～0.84 V（vs.SCE）],具有较为理想的比电容（19.96 F/g）,表明PPy/Co₃S₄在电化学储能方面具有应用前景。更多还原

【Abstract】 Polypyrrole（PPy）had fine conductive properties, cobalt sulfide had a high theoretical specific capacitance, but with low electrical conductivity.Electrochemical energy storage materials with better performance could be obtained by compounding PPy with cobalt sulfide.A composite electrode material（PPy/Co₃S₄）for in-situ growth of Co₃S₄ on PPy nanotubes（PPy-NTs）was designed and synthesized.The effects of temperature and time on electrochemical capacitance were studied.After reaction at 160 ℃ for 6 h, the obtained PPy/Co₃S₄ had a relatively ideal specific capacitance of 19.96 F/g at scan rate of 100 mV/s in 0.5 mol/L H₂SO₄ solution [0.69～0.84 V（vs.SCE）].It demonstrated that PPy/Co₃S₄ had potential application in electrochemical energy storage.更多还原
