Insight into the Photocatalytic Degradation Mechanism for "Forever Chemicals" PFNA by Reduced Graphene Oxide/WO₃ Nanoflower Heterostructures.

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