In this study, the carbon-doped bimetallic organic framework C 60 /MIL-101(Fe,Cu) catalyst was prepared for the first time via solvothermal synthesis method. The catalysts were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and a series of other instruments. At the same time, methylene blue (MB) was used as the target degradation material to investigate the catalytic performance of H 2 O 2 for MB degradation under visible light. The degradation experiment showed that the removal rate of C 60 /MIL-101(Fe,Cu) to MB reached 99.2% within 80 min. Furthermore, cyclic experiments demonstrated good stability and reusability of the catalyst. Finally, the degradation mechanism of the reaction was deduced by quenching experiment, UV–vis diffuse reflection and mott-Schottky plots. The results show that hydroxyl radical (·OH) and superoxide radical (·O 2 − ) play a major role in the degradation of MB during photo-Fenton process.
A one-step solvothermal synthesis technique was employed to fabricate C 60 /MIL-101(Fe) composites. The C 60 /MIL-101(Fe) composites showed a better performance in the degradation of methylene blue (MB) and tetracycline hydrochloride (TCH) when compared to MIL-101(Fe) in the photo-Fenton system, which can be credited to the charge transfer and separation facilitated by the addition of C 60 . Results showed that C 60 /MIL-101(Fe) had the capacity to nearly completely eliminate TCH and MB over a broad pH range. The catalysts demonstrated remarkable catalytic degradation on various organic pollutants and water samples. Through active substance quenching experiments and EPR, it was determined that hydroxyl radical (·OH) is the main factor in the photocatalytic reaction process.
