Abstract
In the present work, the novel TiO2@Ti3C2Tx@ZnFe2O4 composites were synthesized by an ultra-sonicated method. The influence of MXene content and ZnFe2O4 nanoparticles on the photocatalytic performance and degradation efficiency of methylene blue (MB) solution were studied by different measurements such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), Electrochemical impedance spectroscopy (EIS), and ultraviolet (UV)-visible spectroscopy. Among synthesized composites, the optimum photocatalyst showed excellent degradation efficiency of MB solution (100 % in 2 h) and high photocatalytic activity compared to the Ti3C2Tx and TiO2@Ti3C2Tx composites. The degradation mechanism of MB dye by TiO2@Ti3C2Tx@ZnFe2O4 composites was illuminated through kinetic studies. The results demonstrated the key role of ZnFe2O4 nanoparticles in dye removal. In addition, the optimum composite was deposited on nickel foam to construct a novel filter and photocatalytic measurements with long-time experiments had shown the stability and photocatalytic performance of the synthesized filter. Therefore, the optimal TiO2@Ti3C2Tx@ZnFe2O4 composite exhibits significant promise for practical water pollution degrading applications.
