A graphene sponge helps light strip fluorine from ‘forever chemicals’
Researchers developed a graphene-aerogel material that holds a light-activated catalyst and uses both reduction and oxidation reactions to defluorinate several PFAS. After 12 hours of ultraviolet irradiation, it removed 90.2% of the fluorine from PFOA, 65.3% from PFHxA and 51.8% from PFBA.
