A comprehensive review on synthesis methods for transition-metal oxide nanostructures

Abstract

Nanostructured transition-metal oxides exhibit excellent properties, such as ferromagnetic, ferroelectric, photoluminescence and semiconductive behaviors, etc. The band gap and electronic structure of these oxides can be controlled by size and dimensions; they can also be used in a wide range of applications including microelectronics, energy storage, sensors, and biomedicine due to their tunable chemical and physical properties. Here, we give a comprehensive review of the controllable growth of some typical transition-metal oxide nanostructures (e.g., WO_x, FeO_x, ZnO, TiO₂, VO₂, etc.), which can be used to effectively understand the fabrication methods as well as the growth mechanism and inspire their potential applications.
