According to local media reports, this highly sensitive photocatalyst was developed by adding tungsten oxide to the titanium dioxide material. In the experiment, it is irradiated with ultraviolet light whose intensity is equivalent to one thousandth of sunlight. It can catalyze the decomposition of organic matter. If it is coated on the surface of glass and mirrors, the glass and mirror in the room will not occur within three months. Obscure phenomenon. Comparative experiments show that ordinary titanium oxide does not have this ability under this weak ultraviolet irradiation.
Titanium oxide is known as a photocatalyst because it produces a strong oxidative decomposition ability under ultraviolet irradiation, decomposes organic substances such as dirt, and kills microorganisms. Its function is discovered by Professor Fujishima Chiaki of the University of Tokyo. Currently, it is used in the field of environmental protection to manufacture a variety of clean decontamination, dustproof and moldproof products.
Japan has developed a new type of photocatalyst
Tokyo News: The University of Tokyo in Japan recently cooperated with companies to develop a new photocatalyst that can respond to extremely weak light indoors and play a role in cleaning.
