Photoexcited LMCT of Cu²⁺ perfluorocarboxylate for initiating efficient defluorination.

ABSTRACT: Per- and polyfluoroalkyl substances are widely distributed persistent pollutants in water resources that pose serious environmental and health threats. Current per- and polyfluoroalkyl substance destruction strategies are energy-intensive, nonselective, and often generate recalcitrant short-chain fluorinated byproducts. Herein, we report a near-ultraviolet to visible light-driven complete defluorination approach of per- and polyfluoroalkyl substance based on ligand-to-metal charge transfer, wherein commercially available Cu²⁺ salts serves as the electron acceptor from per- and polyfluoroalkyl substance to initiate the defluorination reaction. The feasibility of the degradation reaction is explored under controlled conditions, in which perfluorooctanoic acid is completely degrade
