The applications of nanocrystalline tungsten oxide (WO₃) include electrochromic, photochromic, gasochromic and sonochromic devices, as a photocatalyst for water splitting and purification, for photoelectrochemical decomposition of water, in heterogeneous catalysts. With the excellent gas sensitivity, another important application is gas sensors.

As an important solid lubricating material, tungsten disulfide has a wide range of applications in aerospace, machining, new energy vehicles, medical, electronics, digital and other fields due to its excellent tribological properties. However, the carrying capacity of pure WS2 film is low, and it is easy to absorb moisture and oxidize in humid air, which seriously shortens its service life.

Everyone needs a gift and everyone deserves a gift. A special gift can be much impressive for consumers, clients, parents, brothers, sisters, friends, lovers, couples and anyone receives. 

Among MoS2, WS2, MoSe2, and WSe2, the intrinsic state of WS2 is a bipolar semiconductor with both n-type and p-type electron transport characteristics. Therefore, graphene-like WS2 films have become the current research in the field of two-dimensional atomic layer materials. The following mainly introduces the research status of photoelectric and electrocatalytic performance of WS2 film.

Through the introduction of the preparation methods (Ⅰ) and (Ⅱ) of tungsten trioxide graphene composite materials, we can know clearly that they all have the disadvantages of complex production process, long reaction time, difficult solid-liquid separation, and low yield. 

In addition to in-situ synthesis technology, ex-situ synthesis technology is also a preparation method for tungsten trioxide/graphene composite materials. At present, there are many reports, which mainly include the two steps of pre-preparation of the dispersion of tungsten trioxide nanoparticles and the dispersion of graphene/graphene oxide and the mixing and reduction.

Tungsten trioxide is an n-type wide-band gap semiconductor oxide with low price, easy preparation, stable performance, non-toxic and harmless, and has been widely used in the field of photoelectrochemistry.

When I receive tungsten iridium stream mouth as my product, I think it as an alloy of tungsten and iridium. But after discussion with our manufacturing department, I found what I was thinking is really a mistake. 

The Chinese standard used now is YS/T 854-2012 Tungsten Iridium Stream Mouth, which is under the nonferrous metal industry standard and issued by the Ministry of Industry and Information Technology of the People’s Republic of China.

Among MoS2, WS2, MoSe2, and WSe2, the intrinsic state of WS2 is a bipolar semiconductor, which has both n-type and p-type electron transport properties. Therefore, graphene-like WS2 film has become the current research in the field of two-dimensional atomic layer materials. Hot spot. The following mainly introduces the research status of photoelectric and electrocatalytic properties of WS2 film.
