title: Nitrogen-Doped Ordered Mesoporous Anatase TiO2 Nanofibers as Anode Materials for High Performance Sodium-Ion Batteries.
abstract: Nitrogen-doped ordered mesoporous TiO2 nanofibers (N-MTO) have been fabricated by electrospinning and subsequent nitridation treatment. The N-doping in TiO2 leads to the formation of Ti(3+) , resulting in the improved electron conductivity of TiO2 . In addition, one-dimensional (1D) N-MTO nanostructure possesses very short diffusion length of Na(+) /e(-) in N-MTO, easy access of electrolyte, and high conductivity transport of electrons along the percolating fibers. The N-MTO shows excellent sodium storage performance.
