Room-temperature photocatalytic method for perfluoroalkyl substances’ decomposition

Caption

Perfluoroalkyl substances and fluorinated polymers are efficiently decomposed into fluoride ions under ambient conditions by irradiating visible LED light onto semiconductor nanocrystals. The decomposition is driven by cooperative mechanisms involving light-induced ligand displacement and Auger-induced electron injection, utilizing hydrated electrons and higher excited states.
