Tungsten trioxide crystal is a material with electrical transport properties, which can be prepared by vapor phase transport and annealed under varying conditions. Well, do you know what the effects of oxygen-deficiency on electrical transport properties of tungsten trioxide crystals are?

Monoclinic tungsten trioxide is one of the crystal structure of tungsten trioxide. According to the researchers, they have studied the crystal structure of tungsten trioxide at room temperature by the X-ray oscillation method.

Tungsten oxide is developed as a battery electrode. It has been reported that tungsten oxide electrode material enables ultra-fast charging and discharging. So, it is often used as an anode material for lithium ion batteries. And it has a wide range of applications where a large current or capacity is required, such as uninterruptible power supplies (UPS), large current sources, and power supply stabilizers, etc. Also, it has applications with a focus on energy regeneration properties such as elevators, micro/mild hybrid vehicles and trains.

Yellow tungsten oxide is a well-known γ-ray shielding material with the chemical formula of WO3. It has been reported that WO3 can be compounded with natural rubber (NR) to obtain NR-WO3 composite materials. Some experts adopt hydrothermal method to synthesize Bi2WO6 nanoparticles and obtain WO3 and Bi2O3 particles with similar particle size by ball milling. And they fill these particles into natural rubber with a total mass fraction of 30% to prepare NR-Bi2WO6, NR-WO3 and NR-Bi2O3 composite material.

As a radiation shielding material, Er2O3-WO3-epoxy resin can reduce the damage of radiation to human body, equipment and environment. Some experts have prepared Er2O3-WO3-epoxy resin composites using Er2O3 and WO3 as radiation shielding functional particles and epoxy resin as the matrix. Also, they performed detailed testing and characterization of their microstructure, mechanical properties, and radiation shielding properties.

Yellow tungsten oxide is also well-known as a new radiation shielding material. You know, with the rapid development of science and technology and the increasingly prominent environmental and energy issues, nuclear science and technology have been widely used in various fields such as national defense, industry, environment, and energy, bringing huge economic and social benefits. While it also increases people's exposure to various types of radiation. Therefore, how to minimize the various hazards of radiation is a very important and urgent work.

As a photocatalyst, WO3-TiO2 composite film is an emerging binary semiconductor composite material that can transport and separate photo-generated carriers between semiconductors with different energy levels, prolong the carrier lifetime, thereby improving quantum efficiency.

The photocatalysis of WO3-ZnO composite film is attracting much attention. According to the experts, WO3 is an important non-toxic semiconductor material with a narrow band gap (2.4-2.8eV) that can be used as a catalyst in the photocatalytic reaction for the catalytic degradation of organic substances in sewage. So, the preparation of WO3-ZnO composite film has become a major research hotspot, and its photocatalytic performance has paid much attention.

WO3 is a photochromic material, so WO3-TiO2-ZnO composite film is also a photochromic material with excellent photochromic properties. Well, do you know how to prepare WO3-TiO2-ZnO composite film?

ZnO-WO3 composite film is a composite thin film inlaid with ZnO nanocrystals. More specifically, the composite film adopts amorphous WO3 as a matrix, and ZnO nanocrystals are uniformly distributed in the amorphous tungsten oxide. Some experts have prepared ZnO-WO3 composite film on aluminum foil by sol-gel method, and its modification has been carried out with activated carbon. Taking methyl orange aqueous as simulated organic pollutant, photocatalytic degradation performance of ZnO-WO3 films is studied.
