Local polarization-piezoelectric field promotes water dissociation for efficient fluorinated pollutants defluorination.
Active hydrogen radicals (•H) from water dissociation hold great promise for the defluorination of perfluorooctanoic acid (PFOA). However, the mechanism governing •H generation under a local polarization piezoelectric electric field (LPPEF) remains insufficiently explored in borate-based piezocatalysts, which hinders a...
