Description | In recent years, photocatalysis has been used as an environmentally friendly method for the degradation of organic pigments in water. In this study, $Ce^{3+}/Ce^{4+}$-doped $ZrO_{2}$/CuO as a mixed semiconductor oxide was successfully prepared by a one-step hydrothermal method. The $Ce^{3+}/Ce^{4+}$-doped $ZrO_{2}$/CuO has shown high degradation efficiency of methylene blue (MB), and the maximum degradation percentage was observed to be 94.5% at 180 min under irradiation visible light. The photocatalytic activity increases significantly by doping $Ce^{3+}/Ce^{4+}$ in $ZrO_{2}$/CuO for MB degradation. $Ce^{3+}/Ce^{4+}$ doping is shown to reduce the $(e^{-}/h^{+}$) recombination rate and improve the charge transfer, leading to enhanced photocatalytic activity of materials. The materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), FTIR, EDS, BET and diffuse reflectance spectroscopy (DRS). |
