Yellow tungsten oxide has potential in the application of thermal insulation materials, such as thermal insulation dispersion, as it has good light absorption capability of ultraviolet light and near-infrared light, which means it has high heat insulation performance. And the dispersion also has high light transmittance of visible light.
One-dimensional nanomaterials have attracted much attention as their low dimensionality and special size can bring novel and excellent properties to the product using this type of material as raw material. Therefore, the preparation of nano grain size yellow tungsten oxide powder will also receive attention.
In hydrothermal synthesis, different precursors and modifiers are used to control reaction conditions such as temperature, concentration, pH value, reaction time, and so on. And therefore, yellow tungsten oxide with different crystal phases and morphology can be prepared. However, in most of studies, the formation mechanism of yellow tungsten oxide crystals has not been fully discussed.
