Tungsten Oxide

At present, environmental pollution has become one of the most important concerns of mankind, especially organic pollutants. Their damage to the environment such as water, atmosphere and soil will be damaged if they are not dealt with in time, and cause an irreversible loss. In recent years, photocatalytic degradation has become one of the most important methods for organic pollutants because of its high efficiency, environmental protection and easy operation.  As far as photocatalytic reaction is concerned, titanium dioxide TiO 2  is one of the most studied semiconductors. This is due to its early application, cheapness, ease of handling, large specific surface area, and stability. Photocatalysis has attracted the most attention in the field of wastewater purification and treatment. But what can not be evaded is that TiO 2  band gap is wider (about 3.2 e V), it can only be excited by ultraviolet light, the use of solar energy is limited, photoinduced electron re...

Photocatalysis is a photochemical reaction in the presence of a catalyst, it is a new science and technology. Common photocatalysts include metal oxides (TiO 2 , ZnO, Fe 2 O 3 , Bi 2 O 3 , WO 3 ) and metal sulfides (CdS, MoS 2 , MoSe 2 ). Titanium dioxide TiO 2  is the most white thing in the world, 1 grams of titanium dioxide can paint more than 450 square centimeter area to white. So it's the best paint for making white oil paint. The most well-known is that semiconductor photocatalysis performance of TiO 2 . TiO 2  photocatalysis is widely used because of its high activity, photochemical stability, non-toxic and cheap. Tungsten trioxide TiO 2  is a kind of tungsten compounds that are widely used, It can be used not only for hard alloys, but also for dyes, the most commendable thing is that tungsten trioxide also with excellent photocatalytic performance. Like TiO 2 , WO 3  also has high activity, photochemical stability, non-toxic and so on. If you com...
