Kaltech Tackles COVID-19: Successful Start-up Offers Hints to Japan's Revival
Photocatalyst Discovered by Japanese Researchers The current COVID-19 pandemic has thrown a spotlight on a discovery made by Japanese researchers half a century ago: photocatalyst technology. Photocatalysts are materials that induce a chemical reaction under photoirradiation. Titanium dioxide, the most widely known, causes strong oxidation when exposed to light. Photocatalyst technology leverages this phenomenon to decompose harmful or odor-causing substances into materials like water or carbon dioxide. Fujishima Akira, the former president of the Tokyo University of Science, was studying for...
