Abstract
- In recent years, photocatalysis has been used as an environmentally friendly method for the degradation of organic pigments in water. In this study, Ce<superscript>3+</superscript>/Ce<superscript>4+</superscript>-doped ZrO<subscript>2</subscript>/CuO as a mixed semiconductor oxide was successfully prepared by a one-step hydrothermal method. The Ce<superscript>3+</superscript>/Ce<superscript>4+</superscript>-doped ZrO<subscript>2</subscript>/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<superscript>3+</superscript>/Ce<superscript>4+</superscript> in ZrO<subscript>2</subscript>/CuO for MB degradation. Ce<superscript>3+</superscript>/Ce<superscript>4+</superscript> doping is shown to reduce the (e<superscript>-</superscript>/h<superscript>+</superscript>) 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).
