Light-activated catalyst developed for PFAS degradation
An international research team has developed a light-activated catalyst capable of efficiently breaking down persistent polyfluoroalkyl substances (PFAS). This technology could be used in the future to remove “forever chemicals” from the environment.
PFAS, known as “forever chemicals,” are water-repellent and highly stable substances widely used in products such as non-stick cookware, waterproof clothing, and lipstick. While they do not naturally degrade, PFAS accumulate in water systems, food chains, and the human body. Some studies have linked PFAS to an increased risk of cancer, though their long-term effects on health and the environment remain unclear.
An international team led by the University of Bath has developed a photothermal catalyst that uses sunlight to break PFAS into carbon dioxide and fluoride. The carbon-based catalyst is combined with a rigid microporous polymer to bind PFAS efficiently, allowing degradation under neutral pH conditions commonly found in natural environments.

Learn more about current approaches to produce coatings in a more environmentally friendly way and to give coated products a longer service life in the EC Tech Report Sustainability. In addition, its handpicked content dives deeply into the European Green Deal, its key points and main purpose as well as consequences for the coatings industry.
Technology for broader applications
In addition to degrading PFAS, the technology has potential use as a sensor to detect released fluoride. The research team aims to develop a portable sensor capable of monitoring PFAS concentrations in the environment outside laboratory settings. The team is now seeking industrial partners to scale and optimise this innovative solution.
