Tungsten oxides inorganic semiconductor materials have received considerable attention in recent years because of their unique physico-chemical properties and widespread applications in various areas, such as electrochromic (EC) devices, gas sensors, photocatalytic systems, photoelectrochemical devices, and so on. Recently hydrothermal method has been exploited for the preparation of tungsten oxide micro/nanostructures with different sizes and shapes. Combining with our group's work on the preparation of tungsten oxide micro/nanomaterials, the progress of preparation of tungsten oxide micro/nanomaterials by hydrothermal method is presented. The key influencing factors, such as the choice of reagents, the reaction time and temperature, are discussed in detail. The development trends of the tungsten oxide micro/nanomaterials fabricated by hydrothermal method are also proposed. Contents
