Change the world with Kaltech's original photocatalytic technology

What kind of image do you have when you hear the word photocatalyst?
I've heard the term for a long time, but I'm not sure what it is... Or I don't know how effective it is... I think many people may have the same impression.
Photocatalyst is a catalyst technology that accelerates chemical reactions by applying light. To put it more simply, it is a technology for cleaning substances by exposing them to light and causing them to chemically react with dirty substances.
In fact, this technology has been around for a long time, and it has been used for walls of castles in the old days, and it is still used for various purposes such as the exterior walls of houses and guardrails. And this technology was discovered in Japan about 50 years ago.
Fascinated by photocatalyst, I have been searching for a way to help the world with this perticular technology.

For many years, I have been engaged in device development at a general electric equipment manufacturer. What I have been thinking since then is that home appliances may be obstructing the space.
What is the best device for that? What led us to continue our research is our unique photocatalytic technology. Although the device itself is compact, it is a photocatalyst equipped with the world's first original technology and having the highest performance, and can be applied to various products.
Currently, we are mainly developing products and devices for air, but we plan to continue developing products for water in the future.
And I am proud that it will be a technology that can contribute to the solution of global environmental problems in the future. We will work hard so that our photocatalyst technology will be used in the environmental products that the world needs in the near future.
