Abstract
Hollow SnO2-ZnO hybrid nanofibers are prepared by a single-nozzle electrospinning technique followed with subsequent heat treatment. The structure and morphology of the samples are characterized by x-ray diffraction, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy and transmission electron microscopy. The as-prepared nanofibers are solid, which maintain after annealing up to 400 °C; while they turn to tubular morphology after annealing at 500 °C. After annealing at 700-900 °C, some of the tubular nanofibers combine together. The FTIR results show that poly (vinylpyrrolidone) is completely removed after annealing at 500 °C. The electrode of hollow SnO2-ZnO nanofibers obtained by calcination at 500 °C delivers a high discharge capacity of 546.5 mAh g-1 after 100 cycles at a current density of 100 mA g-1.
