Ternary Hierarchical Flower-Like Ptcute Nanosheets Mediated Photo-Fenton Catalysis for Dye Pollutant Degradation

Abstract

This paper reports the synthesis of hierarchical flower-like PtCuTe nanosheets, confirmed through various characterization techniques. The nanosheets exhibit significant photothermal capabilities, rapidly heating to approximately 90°C under 808 nm NIR. Compared to traditional photothermal catalysts, PtCuTe nanosheets exhibited superior Fenton catalytic efficiency in the degradation of organic dye pollutants, as demonstrated in the RhB degradation experiments. The hierarchical flower-like PtCuTe nanosheets Fenton nanoenzyme exhibited significantly enhanced Fenton catalytic activity for organic dye pollutant degradation compared to conventional photothermal catalysts. Furthermore, this study addressed the limitation of traditional Fenton reactions requiring mildly acidic conditions for effective operation. Additionally, PtCuTe nanosheets exhibit outstanding stability under photothermal conditions, can be reused effectively and environmentally friendly with excellent biocompatibility, underscoring their potential for wastewater treatment applications.
