Energy Storage: Nitrogen-Doped Ordered Mesoporous Anatase TiO₂Nanofibers as Anode Materials for High Performance Sodium-Ion Batteries (Small 26/2016)

On page 3522, Y. Yu and co-workers fabricate nitrogen-doped ordered mesoporous TiO2 nanofibers (denoted as N-MTO) by electrospinning and subsequent nitridation treatment. Nitrogen atoms are successfully doped into the TiO2 lattice, accompanied by the formation of Ti3+ and oxygen vacancies, contributing to the improvement of electronic conductivity of TiO2. When used as an anode for a sodium-ion battery, the N-MTO demonstrates excellent rate capability and superior long cycling performance.
