The electrospun carbon nanofibrous composites (ZnCo2O4/Ag-GO-CNFs) coated with 3D urchin-like ZnCo2O4 nanosheets to form a shish-kebab structure have been prepared by combination of electrospinning, carbonization and hydrothermal treatments. The composition and microstructure of ZnCo2O4/Ag-GO-CNFs were investigated by field emission scanning electronmicroscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), X-ray diffractometer (XRD) and Brunauer-Emmett-Teller (BET) analysis. Interesting, the ZnCo2O4/Ag-GO-CNFs provided a new style of electrode materials and exhibited an excellent speci?c capacity of 459.48 mAh/g at 20 mV s?1. Notably, the speci?c capacity of ZnCo2O4/Ag-GO-CNFs also exhibited a remarkable cycling stability (96.0% retention after 9,000 cycles), which holds great promise for practical applications in energy storage devices as a carbon-based electrode material.
