| الوصف: | Here we report a successful one-step synthesis of vanadium-doped anatase mesocrystals by reactive annealing of NH4TiOF3/PEG2000 mesocrystal precursors with NH4VO3. The formation solid solution Ti1−x V x O2 with vanadium content up to x = 25 at% inheriting the structure of mesocrystals is observed for the first time. The doping mechanism via vapor phase transport of vanadium is proposed. The Ti1−x V x O2 mesocrystals exhibit improved specific capacity of 175 mAh g−1 (compared to 150 mAh g−1 for pure anatase phase) and decreased potential gap between charge and discharge processes. |
