Tokyo University of Science, Tokyo University of Agriculture and Technology, and Manned Space Systems Co., Ltd. (JAMSS) have signed a joint research agreement on "manufacturing and technology demonstration of air purification equipment using photocatalysts".
With the advent of the era of space travel by the private sector, there is a need to improve the quality of life (QOL).On the other hand, in long-term life in a closed space such as a space station, volatile organic compounds that cause "odor" such as methane produced in the intestine, urine, and acetaldehyde emitted from the skin in addition to carbon dioxide from exhaled breath ( Accumulation of VOC) is known.In addition, although favorite odors such as aroma are considered to be effective from the viewpoint of relaxation, there is a concern that they will become "smell" for other people in a closed space.
Therefore, JAMSS thought that a simple air purification device that could be placed anywhere would be necessary to make the stay in space more comfortable for space travelers (improved QOL), and focused on photocatalysts that are effective in removing VOCs.We will proceed with joint research targeting the demonstration of air purification technology at the International Space Station with Tokyo University of Science and Tokyo University of Agriculture and Technology, which are world leaders in this technology.
Photocatalyst technology is a technology that Japanese researchers have discovered and established its effects, and has the characteristics of a simple structure and maintenance-free.In order to support the era of private space travel with Japan's leading technology, we aim to establish a technology with an international competitive advantage.In addition, photocatalysts have the potential to lead to technologies that are indispensable for long-term stay in space, such as sterilization, water purification, and fuel generation, and we will further develop them as the next step in this joint research.
* Manned Space Systems Co., Ltd. (JAMSS) is a part of the International Space Station (ISS), ground control work of the Japanese Experiment Module "Kibo", training and health management of astronauts working at "Kibo", etc. Engaged in work related to the operation of "Kibo".
