Abstract α-Fe 2 O 3 /CNT nanocomposite was successfully synthesised via in-situ co-precipitation method. The structural properties were studied by X-ray diffraction (XRD), Transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The nanocomposite was uniformly coated on dried shell of Lagenaria siceraria (LS) and directly used as the working electrode for electrochemical investigation. It was found that the as-prepared Fe 2 O 3 /CNT-LS electrode exhibited high capacity, better cycling stability and rate capability. This improved performance was attributed to the spongy, fibrous and networking structure of Lagenaria siceraria dried shell, which allowed fast diffusion of electrolyte ions and structural stability. This Fe 2 O 3 /CNT-LS electrode can be promising candidate for energy storage applications.

Fe 2 O 3 /CNT纳米复合材料包覆干燥紫薇壳电极用于电化学电容器的高效电化学性能

摘要 采用原位共沉淀法成功合成了α-Fe 2 O 3 /CNT纳米复合材料。通过X射线衍射（XRD）、透射电子显微镜（TEM）和X射线光电子能谱（XPS）研究了结构特性。将纳米复合材料均匀地包覆在干燥的 Lagenaria siceraria (LS) 壳上，并直接用作电化学研究的工作电极。结果表明，所制备的 Fe 2 O 3 /CNT-LS 电极具有高容量、更好的循环稳定性和倍率性能。这种改进的性能归因于 Lagenaria siceraria 干壳的海绵状、纤维状和网络结构，它允许电解质离子的快速扩散和结构稳定性。这种 Fe 2 O 3 /CNT-LS 电极可能是储能应用的有希望的候选者。
