Abstract

The photochemical transformation of polyfluorinated alkyl substances (PFAS) leads to structural unzipping to give rise to fluoride and further degradation products depending on (i) the type of photocatalyst as well as on (ii) microporous coatings or reaction environments. Here, a substantial increase in photocatalyst performance is observed by coating graphitic carbon nitride (g-C₃N₄) with an intrinsically microporous polymer (PIM-1) to enhance interaction with heptadecafluoro-1-nonanol (as a PFAS model).
