Titanium dioxide is a material with notable photocatalytic properties. When a titanium dioxide photocatalyst is exposed to light in the presence of water and oxygen, a reaction occurs that generates strong oxidizing power on the surface of the photocatalyst. This breaks down and neutralizes harmful organic substances that come into contact with the photocatalyst.

Back in 1972, Japan was home to a breakthrough in photocatalysis research. Technology derived from this research is improving lives today—purifying air and water and keeping food fresh. Looking ahead, we see the potential for new applications of photocatalysis in fields such as medical care, energy, and the environment.

Since our company’s founding, Kaltech has continued to do applied research on photocatalysts. We’re committed to enriching the lives of people everywhere by harnessing the knowledge and unique technologies we have gained through our research.

Kaltech’s vision is to create an “infrastructure for life” through photocatalysts and to share the resulting benefits with people all over the world.
