NANOTECHNOLOGY IN REMEDIATION OF WATER CONTAMINATED BY POLY- AND PERFLUOROALKYL SUBSTANCES: A REVIEW
Zhang, W., D. Zhang, and Y. Liang.
Environmental Pollution 247:266-276(2019)

Literature has shown that PFOA can be effectively decomposed in the presence of either TiO2-based, Ga2O3-based, or In2O3 -based nano-photocatalysts under ultraviolet irradiation. This article reviews and compares the decomposition abilities and mechanisms of different nano-photocatalysts. Nano-sized In2O3 photocatalysts were found to have the best potential in PFOA decomposition and the decomposition performance is closely related to the specific surface area and the number of photogenerated holes on the surfaces of In2O3 nanostructures. In addition to a detailed review of the published studies, future prospects of using nanotechnology for PFAS remediation are also discussed.
