Water contamination with "forever chemicals" like per- and polyfluoroalkyl substances (PFAS) poses significant toxicity to the environment. Since they are most persistent synthetic chemicals that hardly degrade in natural environment carcinogenic humans, there is an urgent need discover novel processes for destroying PFAS. Herein, we report on design of a reduced graphene oxide (r-GO)/WO3 nanoflower (WO3-NF)-based heterostructure harnessing 365 nm light-driven photocatalytic oxidation reduction process toward degradation perfluorononanoic acid (PFNA). Moreover, reported data reveal using r-GO/WO3-NF photocatalyst, 100% PFNA 14% defluorination can be achieved presence isopropyl alcohol as hydroxy radical (•OH) quencher or glucose hot hole (h+) after exposure light 22 h.
