摘要

Multichannel hollow TiO2 nanofibers were synthesized via a facile single-nozzle electrospinning method based on phase-separation mechanism. Compared to normal TiO2 nanofibers, hollow TiO2 with higher surface area gave rises to a higher surface contribution and ensured a short diffusion path for ion transport. Thus hollow TiO2 demonstrated superior cyclic ability and excellent rate capability.
