abstract = {Per- and polyfluoroalkyl substances (PFAS) are a diverse group of synthetic fluorinated
compounds widely used in industrial and consumer products due to their exceptional
thermal stability and hydrophobicity. However, these same properties contribute to their
environmental persistence, bioaccumulation, and potential adverse health effects, including
hepatotoxicity, immunotoxicity, endocrine disruption, and increased cancer risk. Traditional
water treatment technologies, such as coagulation, sedimentation, biological degradation,
and even advanced membrane processes, have demonstrated limited efficacy in removing
PFAS, as they primarily separate or concentrate these compounds rather than degrade
them. In response to these limitations, photoassisted processes have emerged as promising alternatives capable of degrading PFAS into less harmful products. These strategies
include direct photolysis using UV or VUV irradiation, heterogeneous photocatalysis with
materials such as TiO2 and novel semiconductors, light-activated persulfate oxidation
generating sulfate radicals, and photo-Fenton reactions producing highly reactive hydroxyl
radicals. Such approaches leverage the generation of reactive species under irradiation
to cleave the strong carbon–fluorine bonds characteristic of PFAS. This review provides a
comprehensive overview of emerging photoassisted technologies for PFAS removal from
water, detailing their fundamental principles, degradation pathways, recent advancements
in material development, and integration with hybrid treatment processes. Moreover, it
discusses current challenges related to energy efficiency, catalyst deactivation, incomplete
mineralization, and scalability, outlining future perspectives for their practical application
in sustainable water treatment systems to mitigate PFAS pollution effectively.},
