A research team led by Prof. Kang Yanbiao from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has made a significant discovery in the field of environmental chemistry. They developed a novel photocatalyst named KQGZ, which can photocatalytically defluorinate polyfluoroalkyl and perfluoroalkyl substances (PFAS) at a low temperature range of 40°C–60°C. This finding has been published in Nature.
