Photocatalysis, as a new wastewater treatment technology, has shown broad application prospects in the advanced treatment of organic wastewater. In addition, photocatalysts are also widely used in building decoration markets and indoor cars. Photocatalysis process has almost no selectivity for the degradation of organic matter, and can completely mineralize organic pollutants, without secondary pollution.

With the increasing problems of energy and environment, the pollution of water resources by organic matter is particularly prominent, which not only affects human health, but also consumes a large amount of energy to eliminate such pollutants. Therefore, the development of new materials using photocatalytic technology to solve pollution has become a new research direction.

At present, some new tungstate photocatalytic materials with visible light effect have been discovered by researchers. Semiconductor materials such as tungstate have good application prospects due to their unique structure and physicochemical properties, such as magnetic devices, scintillators, corrosion inhibitors and catalysts, which have become a research hotspot in recent years. For example, the catalytic material Bi₂WO₆ (band gap is only about 2.8eV), which is faster than the visible light response photocatalysis of TIO₂, can mineralize harmful substances such as chloroform and acetaldehyde under visible light, and degrade them into CO₂.

Because of its excellent properties such as high hardness, high red hardness, high compressive strength, high wear resistance and good corrosion resistance, superfine tungsten carbide powder is known as "industrial teeth" and widely used in almost all sectors of the national economy and various fields of modern technology. As the main material of cemented carbide, tungsten carbide has been devoted to improving its contradictory properties of hardness and toughness.

In recent years, the research of two-dimensional layered materials has attracted the attention of scientists, especially the rapidly developing graphene nanomaterials, which have the characteristics of high strength, excellent conductivity and thermal conductivity, and are widely used in the field of sensors. Graphene is known as the king of new materials. However, graphene is a two-dimensional material with zero band gap and can not be used as channel layer of transistors, which limits its further application in nano-electronic devices and photoelectric conversion.

Because of its high melting point and high high temperature mechanical properties, tungsten metal is widely used in high temperature components, lighting, national defense and other fields. Besides, tungsten metal has the advantages of low thermal expansion coefficient and anti-sputtering. It is the most promising candidate wall material for fusion reactor. However, tungsten has some shortcomings, such as low temperature brittleness and recrystallization brittleness, which lead to brittleness and difficult to process and shape, and affect its application.

With the increasing shortage of fossil fuels and the harsh environmental pollution, photocatalytic technology has received a great attention.It is applied in transformation of solar energy, degradation of organic pollutants. The advances in photocatalytic technology rely on the function of semiconductor materials.

Recently, Dyze Design, a developer of 3D printer accessories in Montreal, Canada, released its latest product, Tungsten Carbide Nozzle. This is an important accessory for ultra-high performance 3D printers. It offers high wear resistance and performance for almost any 3D printer brands such as Ultimaker, Prusa, Lulzbot, Raise3D and Robo. Its will greatly increase speed of printing, which means lower energy consumption and cost.

With the continuous development of material science, the structure of materials is developing toward two-dimensional direction, which provides an important way to give full play to the potential of materials. Thin film science is a very important field for the development of new materials and devices. Target is the key material in surface coating technology. The performance of target directly affects the performance of film, and the performance of target is mainly determined by the production process of target.

As a new type of wastewater treatment technology, photocatalysis can be widely used in the building decoration market and indoor vehicles. The photocatalytic process has almost no selectivity for the degradation of organic matter, and can completely mineralize organic pollutants without secondary pollution.  The unique advantages of simple equipment, low investment and good effect.
