At the core of Müller’s study, published in the Journal of Catalysis, is the development of nanocatalysts designed to remediate PFAS compounds, specifically targeting Perfluorooctane sulfonate (PFOS). PFOS, once a common ingredient in stain-resistant products, has seen a global phase-out due to its health risks, yet it remains a persistent challenge in water pollution. The innovation lies in Müller’s use of pulsed laser in liquid synthesis to create nanocatalysts that can be precisely controlled and scaled, offering an unparalleled advantage over traditional chemical methods.
