A single-source molten salt synthesis of uniform octahedral Na2Ti3O7 particels composed of nanorods
2018
Na2Ti3O7, as one of the most potential anode electrode materials, is expected to play an important role in various fields. In this work, we synthesized uniform hollow octahedral Na2Ti3O7 particles through directly sintering a kind of precursors obtained by (NH4)2TiF6 and NH4OH in the presence of sodium-containing cationic polyacrylamide. XRD, SEM, TEM were used to characterize precursors and Na2Ti3O7 particles. In addition, the synthesis conditions and the formation mechanism were discussed in detail. This single-source molten salt method is flexible, efficient and controllable. Moreover, the strategy of this method makes it possible for us to synthesize other sodium titanate materials.
