Bismuth tungstate is a layered structure, and bismuth tungstate has a photocatalytic performance under visible light. It can photolysis and photodegradation of organic pollutants in visible light. Therefore, bismuth tungstate has a good application prospect in many related fields.

How to reduce all kinds of radiation intensity, effectively protect the environment and protect human health has been urgently mentioned on the agenda. Chinese researchers have developed a new type of tungsten radiation protective clothing, which reduces the cost through technology. The implementation of the process is as follows:

Photocatalysis is a technology that uses the energy of natural light to convert into chemical reaction and produces catalytic technology to decompose organic substances which are harmful to the human body and the environment, and will not cause the waste of resources and the formation of additional pollution. Bismuth tungstate is a typical representative of new photocatalysis. The research is focused on the development of a new type of Bi₂WO₆ based composite photocatalyst. Modification are the effective means to improve the photocatalytic level of bismuth tungstate.

Energy conservation is a problem that must be considered in the sustainable development of every country's economy. In the energy consumption of many countries, building energy consumption accounts for about 30 ~ 40% of the national energy consumption, while the energy consumed through glass doors and windows accounts for more than 50% of the energy consumption of the building. If the transmission of near infrared light is reduced, the heat shielding effect will be greatly improved. Transparent heat insulation coating and transparent heat insulation film have bright prospects for economic, convenient use and good insulation effect.
