摘要
最近，金属卤化物在储能设备领域受到了广泛关注。本研究采用水热法合成了硒化锡-聚吡咯（SnSe-PPy）纳米复合材料，并对其超级电容行为进行了研究。通过 X 射线衍射（XRD）、傅立叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）和电化学特性分析了合成的 SnSe-PPy 纳米复合材料。XRD 证实了正交锡硒的存在，傅立叶变换红外光谱结果显示了聚吡咯的存在。通过循环伏安法和电静态充放电法研究了 SnSe-PPy 纳米复合材料的超级电容行为。SnSe-PPy 纳米复合材料在 10 mV sec -1 时的比电容为 223 F g-1。聚吡咯的加入增加了材料的导电性，改善了其超级电容行为。
Superior electrochemical performance of SnSe-PPy nanocomposites for supercapacitor application
Recently, Metal chalcogenides have received considerable interest in the field of energy storage devices. In this work, tin selenide-polypyrrole (SnSe-PPy) nanocomposite has been synthesized by hydrothermal method and its supercapacitive behavior is investigated. The synthesized SnSe-PPy nanocomposite is analyzed by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and electrochemical characterization. XRD confirms the existence of orthorhombic SnSe, and the FTIR result reveals the presence of polypyrrole. The supercapacitive behavior of SnSe-PPy nanocomposite is studied by cyclic voltammetry and galvanostatic charge-discharge studies. SnSe-PPy nanocomposite delivers the specific capacitance of 223 F g-1 at 10 mV sec -1. The addition of polypyrrole increases the conductivity of the material and improves its supercapacitive behavior.
