Tungsten Trioxide (WO3), as a material with high gas sensitivity, high sensitivity and short response time, can be used as a gas sensor, and has been widely used in life and industry. A gas sensor is a kind of transducer that converts a certain volume fraction of gas into corresponding electrical signals. Compared with traditional gas sensors, a gas sensor made of Tungsten Trioxide has high sensitivity, good stability, short response time and easy preparation, and can be used for…

In recent years, as a highly sensitive material, Tungsten Trioxide (WO3) has many advantages, such as short response and recovery time, appropriate response temperature, and easy measurement and control. It can be used in the military of?national defense, and has attracted people’s concern. Gas sensing property means that when a certain gas (such as ethanol, methane, hydrogen.) is introduced, the color of the material changes reversibly. The greater the variation, the better the gas sensitivity. Tungsten Trioxide is such a…

Tungsten Trioxide (WO3) thin film is a kind of dingal material with large transmittance change, good reversibility, low relative price, long life, non-toxicity and environmental protection, and it is the earliest and most widely used electrochromic material. The application of this electrochromic material is hidden in our daily life. For example, it can be made into smart windows, which can save energy, dim light, control heat load and other dings. Therefore, in order to study the properties of Tungsten Trioxide…

Tungsten Trioxide（WO3）is an electrochromic semiconductor material with early discovery, study and application widely. It has good chemical stability, no toxicity, great difference in optical properties between coloring and fading, and long cycle life, so it has been widely used in the field of energy conservation. Electrochromism is a phenomenon where the optical properties of materials (reflectivity, transmittance, absorption rate, etc.) undergo stable and reversible color changes under the action of an applied electric field, which is manifested as reversible color…

In recent years, Tungsten Trioxide (WO3) has been favored by researchers for its many special properties. For example, when WO3?is used as a photocatalyst,?it can be used for air purification, self-cleaning, inorganic and organic synthesis, hydrogen production by photolysis of water and control of oxygen and heavy metals pollution.That’s all thanks to its photocatalytic property. The photocatalytic principle is based on the redox ability of photocatalyst under illumination, which can achieve the purposes of purifying pollutants and synthesizing conversion substances.…

With the continuous progress of science and technology,?human?quality of life has been greatly improved, but must the development of science and technology bring a good side to mankind? Not necessarily, but also has negative effects. For example, people pay more attention to pollution, which is the “sequela” left by the treatment technology failing to keep up with the development of science and technology. In order to reduce the pollution level, relevant researchers are committed to finding an efficient and environmentally?protection…

Tungsten Trioxide (WO3) is a kind of relatively?stable tungsten oxide. Because of its electrochromic, photochromic, gas-chromic and other special properties, WO3?smart glass is a product that meets the needs of modernization. How to apply Tungsten Trioxide to smart glass? Tungsten Trioxide has become an important research hotspot of many high-tech materials due to its?characteristics. Electrochromism refers to the reversible color change of materials driven by electric field. For example, in electrochromic devices, the core is an electrochromic layer, whose performance…

Tungsten Trioxide (WO3), as an N-type semiconductor material with good mechanical stability, photoelectric effect and electrochromic characteristics, is favored in the field of energy storage and used by researchers at home and abroad to replace cobalt in lithium-ion batteries. With the gradual decline of subsidies for new energy vehicles and the raid on Covid-19 in 2019, the shortage of cobalt resources and high costs have become increasingly prominent. Therefore, getting rid of dependence on cobalt has become an important direction…

Tungsten Trioxide ceramics are a metal cermet, which means that people add a certain proportion of Tungsten Trioxide into the clay for making ceramics to make ceramics with the advantages of high temperature resistance and non-friability. Compared with traditional ceramics, it not only retains the original advantages, but also increases the high temperature resistance, chemical corrosion resistance, good thermal conductivity and other advantages of tungsten. Tungsten Trioxide is an essential high-tech material with the characteristics of nonlinearity, high dielectric constant,…

Tungsten Trioxide (WO3) has different morphologies and structures at different temperatures. WO3?has at least five structural phase transitions between -40 and 740 degrees Celsius, and the hexagonal phase is a stable morphological structure between 200 and 400 degrees Celsius. The crystal form of hexagonal tungsten trioxide is distorted cubic ReO3 structure, which is also called layered structure. The crystal structure of tungsten trioxide is a distorted anorthite structure, that is, the absence of cations appears in the formal structure. However,…
