Promoted perfluoropolyether catalytic degradation performance of MnO x nanoflower catalysts modified by transition metals

Key Points

• The study aims to develop efficient catalytic methods for degrading fluorinated polymers, focusing on PFPEs.
• Investigated the catalytic performance of MnOx nanoflower catalysts modified with transition metals.
• Evaluated degradation efficiencies through various experimental setups.
• Analyzed the persistence and toxicity of PFPEs during the degradation process.
• Transition metal-modified MnOx catalysts significantly enhanced degradation rates of PFPEs, with a reduction rate of up to 85% observed.
• The catalytic efficiency varied by metal type, indicating optimal modification strategies for degradation.
• Findings suggest that these catalysts can potentially mitigate environmental impacts associated with fluorinated polymer waste.
