With the rapid advancement of science and technology, sensors, as the core components for information acquisition, have their performance directly determining the technological progress and application outcomes in numerous fields. Be it smart wearable devices, environmental monitoring systems, medical diagnostic instruments, or industrial automation production lines, sensors play an indispensable role. As the requirements for sensor performance continue to rise, researchers are dedicated to exploring novel sensitive materials. Tungsten disulfide nanosheet (WS₂ nanosheet) has demonstrated remarkable application potential in the sensor field owing to its unique physical and chemical properties, and has thus become one of the research hotspots.

Blue Tungsten Oxide (BTO, commonly referring to WO3-x) is a non-stoichiometric tungsten oxide with the following characteristics:

I. Color and Appearance

It appears as blue or dark blue powdered crystals, with the shade of blue correlated with the concentration of oxygen vacancies.

Brown tungsten oxide, typically referring to tungsten dioxide (WO₂), is an inorganic compound composed of tungsten and oxygen elements. It is an important transition metal oxide with unique physical and chemical properties. Here are some key characteristics of brown tungsten oxide:

Yellow tungsten oxide (chemical formula: WO₃) is an important transition metal oxide with unique physical and chemical properties, and is widely used in various fields such as energy, environmental protection, and electronics. Here is a brief introduction to its main characteristics:

In daily life and industrial production, the operation of mechanical equipment relies on the support of lubricating materials. Lubricating materials play a crucial role as they can reduce friction and wear between mechanical components, lower energy consumption, and extend the service life of equipment. In recent years, tungsten disulfide nanosheet (WS₂ nanosheet), as a new type of lubricating material, has gradually become a "star material" in the lubrication field, thanks to its unique structure and excellent properties.

Tungsten disulfide nanosheet (WS₂ nanosheet) consists of tungsten and sulfur. Its structure resembles a sandwich, with one or more layers of tungsten atoms sandwiched between two layers of sulfur atoms, and these layers are held together by weak van der Waals forces. This unique layered structure endows the WS₂ nanosheet with many excellent physical and chemical properties, making it highly effective in the lcatalysis field.

In the world of nanomaterials, the tungsten disulfide nanosheet (WS₂ nanosheet) is gradually becoming a focal point of scientific research. This material is widely used in the energy field due to its unique physical and chemical properties. As global demand for sustainable energy continues to grow, the WS₂ nanosheet offers new possibilities for addressing energy challenges.

Yellow tungsten oxide (WO₃), as a novel and highly efficient catalyst, demonstrates remarkable potential in various industrial catalysis fields due to its unique physicochemical properties. It not only possesses excellent photoelectric properties but also plays a crucial role in key areas such as environmental governance and energy conversion, offering new possibilities for the development of the green chemical industry.

In today's world where issues of global climate change and environmental protection are increasingly urgent, the scientific and industrial communities are dedicating unprecedented enthusiasm to the research of efficient and eco-friendly catalyst materials. In this journey of exploring green technology, yellow tungsten oxide, this seemingly unremarkable chemical substance, is quietly leading a green revolution with its unique catalytic performance and environmental characteristics.

Yellow tungsten oxide, with the chemical formula WO₃, is an important member of the tungsten oxide family, appearing as yellow or yellow-green powdered crystals. Its color variation is closely related to its crystal size: it exhibits a bright yellow color when the crystal size is approximately 1.5 micrometers and shifts to green when the crystal size increases to 15 micrometers. Despite the difference in appearance color, its basic characteristics remain consistent.
