CuS–NiFe/NF nanoflowers mediated photothermal enhanced Fenton-like catalysis for wastewater treatment

Year: 2025

Type: article

Abstract: In this study, CuS with an appropriate band gap and high catalytic activity was synthesized on its surface using a one-step method that employed nickel foam as a precursor. Ultimately, the CuS–NiFe/NF catalyst was successfully produced. The catalysts were characterized through various analytical techniques, including scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). When driven by near-infrared light, low-concentration CuS–NiFe/NF solutions can elevate the temperature by nearly 60° Celsius. The introduction of high bandgap CuS into the material enhances its photothermal performance. Meanwhile, the simultaneous presence of Cu and Fe atoms promotes the electron migration rate, exhibiting superior dye degradation capability across all evaluated parameters. Even after multiple uses, it maintains photothermal stability and resistance to degradation. More importantly, both CuS–NiFe/NF and its degradation products are environmentally friendly, demonstrating substantial potential for practical applications. This catalyst provides a novel approach for wastewater treatment.
