摘要：
Nitrogen-doped ordered mesoporous TiO2 nanofi bers (N-MTO) have been fabricated by electrospinning and subsequent nitridation treatment. The N-doping in TiO2 leads to the formation of Ti3+, 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.
