Bismuth Tungstate

Tungstate and other semiconductor materials because it’s unique structure and physico-chemical properties, increasingly people's attention. Tungstate which has a light responsive photocatalysts is: bismuth tungstate, zinc tungstate, and silver tungstate, these tungstate semiconductor photocatalysts facilitate removal and degradation of organic pollutants and decomposition of water.
Wherein the bismuth tungstate as a new photocatalyst, the chemical formula of it is Bi2O12W3 and molecular weight is 1161.4736. There is some related system number of bismuth tungtate as follows: 13595-87-4, EINECS number: 237-033-7. In addition, it is an efficient, non-toxic, inexpensive material, in terms of the dielectric, sterilization and photocatalysis has a wide range applications. Meanwhile bismuth tungstate is kind of narrow gap material which has diverse topography. Thereby controlling its production conditions can produce nano bismuth tungstate with different morphologies and structure, so that effectively improve their physical and chemical properties to improve the catalytic performance and develop the new applications.
