New Catalyst Breaks Down PFAS

Scientists from the University of Bath, in collaboration with the University of São Paulo, University of Edinburgh, and Swansea University, have developed a prototype carbon-based photocatalyst capable of breaking down polyfluoroalkyl substances (PFAS). PFAS are persistent 'forever chemicals' found in various products and accumulate in the environment and human body, posing potential health risks. The new catalyst, combining carbon nitrite with a rigid microporous polymer, uses light to degrade PFAS into carbon dioxide and fluoride, especially at neutral pH. This technology could also be adapted for use in a portable sensor to detect PFAS levels. The research team, led by Professor Frank Marken, is now seeking industrial partners to scale up and optimize the technology.
