Pulsed Electrolysis Unlocks Non-Noble-Metal Catalysis for Per- and Polyfluoroalkyl Substance Defluorination in Water.
Per- and polyfluoroalkyl substances (PFAS) pose severe threats to human health and global sustainable development. Electrochemical reduction (ECR) provides a promising reagent-free strategy for PFAS defluorination, yet its practical deployment is severely limited by cathodic PFAS repulsion and C-F bond stability. Herei...
