In recent years, in order to increase the attention of the living environment, development of the new technology for reducing volatile organic compounds (VOCs), PM2.5, odor, bacteria, and virus is progressing. Especially, the photocatalyst expected as environment purification material, because it can decompose organic matter with light as an energy source.
Toshiba Materials Co., Ltd., and Toshiba Corporation developed high performance visible light response tungsten oxide (WO3) photocatalyst with using technique of tungsten processing. By constructing this WO3 photocatalyst on the wall of the living space, public space, or office, it is possible to purify the air. This report introduces about the development of the photocatalyst, high performance due to the metal oxide additives, and application examples of the real space.
