Overview

• A University of Adelaide team led by Dr. Cameron Shearer tuned a CdIn2S4 photocatalyst to target PFAS-protective fluorine atoms and achieve complete degradation under sunlight.
• The catalyst shatters the strong carbon–fluorine bonds that make PFAS persistent, isolating fluoride ions in a low-energy, chemical-free process.
• Peer-reviewed publication in the journal Small confirms total PFAS decomposition without added reagents and validates the material’s photocatalytic efficiency.
• The recovered fluoride can be purified for reuse in healthcare products like toothpaste or as fertilizer additives, turning waste into a valuable resource.
• Colleague Mahmoud Gharib is spearheading efforts to enhance catalyst durability and integrate the technology into pilot-scale water treatment systems.
