VO2(B) nanospheres: Hydrothermal synthesis and electrochemical properties

Abstract Monodisperse VO 2 (B) nanospheres with an average size of 100 nm were synthesized by hydrothermal method. Experiments showed that the surfactant octadecyl-amine played an important role during the formation of the nanospheres, and possible mechanism was suggested. Moreover, the potential uses of VO 2 nanospheres were primarily probed as electrodes for lithium-ion batteries.
