Title: Preparation of porous Si and TiO2 nanofibres using a sulphur-templating method for lithium storage

We prepared highly porous Si/TiO2 composite nanofibres using a unique sulphur-templating method combined with electrospinning. The structure, morphology, surface area, phase and composition of these nanofibres were characterized using Raman spectroscopy, scanning electron microscopy, powder X-ray diffraction, surface area analyser and thermogravimetric analyser. The specific surface area of Si/TiO2 porous NFs is as large as 387m2g-1, whose silicon capacity can be maintained above 1580mAhg-1 in 180 cycles.
