Effective Destruction of PFAS in Water by Modified SiC-Based Photocatalysts
Abstract
The main objective of this study is to develop and demonstrate a novel catalyst materials ability to enhance the ultraviolet (UV) based carbon-fluorine (C-F)bond cleavage using a silicon carbide (SiC) catalyst composited with single atom platinum catalyst (SAC Pt). The team investigated both perfluorooctanoic acid (PFOA), perfluoroctane sulfonic acid (PFOS) and byproducts of the reaction. The research will seek to answer specific technical questions on catalyst performance that will be necessary for scale-up and deployment of this technology: (1) evaluating the catalyst performance as measured by reduced reaction time relative to titanium dioxide (TiO2), (2) measuring the percent destruction of per- and polyfluoroalkyl substance (PFAS) molecules and monitoring daughter products, and (3) understanding catalyst degradation pathway and ultimate lifecycle of the material in order to assess potential for field deployment
