Tungsten Trioxide Nano Material

Compared with the conventional tungsten oxide material, the nano-tungsten oxide material has quantum size effect and surface effect and plays an important role in the interface-related field. Three-dimensional tungsten oxide nano-materials with large surface area, surface active centers, high crystallinity and loose network structure and other characteristics, the gas sensitivity is expected to show more excellent performance.

So far, many researchers have tried to build a tungsten oxide nanowire material with three-dimensional composite nanostructures, such as tungsten oxide three-dimensional network structure. However, these three-dimensional network-like structures have many nano-structures intersected with each other by nanowires. These nodules are often physically connected to each other. They are prone to microstructural changes under the influence of changes in the external environment, leading to poor contact between the nanostructures, leading to their lack of stability.

On the other hand, in the prior art, the method for preparing the nanofilm often can not assemble a single three-dimensional composite nanostructure unit. The prepared three-dimensional composite nanostructures are often sticky island structure, agglomeration serious, the surface effect, quantum size effect is not obvious. And can not control the growth of tungsten oxide with high precision, hinder the process of miniaturization of the functional nano-material device, and make the material fail to achieve the desired performance.

Therefore, effectively tailoring tungsten oxide three-dimensional composite nanostructures with excellent surface effect and quantum size effect has become a scientific problem. Aiming at the above problems, the tungsten oxide three-dimensional composite nanostructure material is improved, which helps to improve the material stability and the specific surface area.
