Abstract: Perfluoroalkyl substances (PFAS), including perfluorooctanoic acid (PFOA), are highly persistent environmental pollutants due to their strong carbon-fluorine bonds. Conventional degradation methods often require extreme conditions, making them inefficient and environmentally taxing. This study explores a visible light-catalyzed approach to degrading organofluorides using a ruthenium-based photocatalyst, [Ru(bpy)₃]²⁺. Under visible light irradiation (400–700 nm), the photocatalyst generates reactive species capable of initiating PFOA decarboxylation, potentially yielding smaller, less harmful byproducts. The study evaluates the catalyst’s efficiency under varying light sources and environmental conditions to optimize degradation pathways. This work highlights a sustainable alternative for PFAS remediation, offering a promising strategy to mitigate their environmental and health impacts.
