Why Tungsten Trioxide Is A Promising Photocatalyst Material?

photocatalyst picture

Tungsten trioxide (WO3) is one of the earlier studied photocatalysts. There are other promising photocatalysts such as titanium dioxide, iron oxide and so on. But what makes tungsten trioxide one of the earliest materials studied in the field of phtocatalysts? This is due to the light stability of tungsten trioxide, a wide range of sources, and it is environmental friendly. It is no wonder that it will be favored by researchers.

Nanometer Metal Structures Using 3D Printing: Even Tungsten Material Is Achievable

3D print picture

At present, one of the difficulties of 3D printing technology is the using of refractory metal for printing, especially metals with high melting points such as tungsten, chromium and bismuth, nor the nanometer powders. This means that it is also difficult to apply 3D printing technology to nanometer tungsten trioxide powder. Over the years, scientists from all over the world have worked on new processes that can be cost-effective and achieve the desired performance requirements.

A Hydrothermal Synthesis Method of Tungsten Trioxide Photochromic Material

tungsten trioxide picture

Tungsten trioxide is an excellent photochromic material that turns blue under ultraviolet light. So, what is photochromism? Photochromism means that compound A can produce product B with different structure and spectral properties through specific chemical formula when subjected to illumination with wavelength λ1, and B can be reversibly generated under the action of light or heat with wavelength λ2.

Super-Hydrophobic Tungsten Trioxide with Special Wettability

tungsten trioxide picture

Nowadays, research on the wettability of tungsten trioxide materials is not deep enough, although thanks to its unique optoelectronic properties, WO3 has been used in many fields such as photochromism, photocatalysis, electrochromism, sensors and information storage. These areas are also well-known applications of WO3, as many people know that tungsten trioxide is a common n-type semiconductor material. However, the lack of research on the wettability of WO3 will undoubtedly greatly limit the application of tungsten trioxide materials in practical industries. Therefore, the combination of tungsten trioxide material and wetting properties will have important theoretical and practical significance in the increasingly mature and application of WO3 preparation methods.
