Abstract
This graphical abstract describes in general the treatment processes of dye-polluted water using the prepared samples. Activated carbon undergoes both adsorption and catalytic oxidation processes, further the photocatalytic efficiency of each catalyst supported by activated carbon enhanced the removal of dye completely in a short time in addition to adsorption process in the early irradiation time.Activated carbon (AC) prepared from activation of ground peach stones with phosphoric acid under flowing air was used as a support for CeO2 and ZnO nanoparticles through hydrothermal method at 200℃ for 120 min and followed by the calcination at 400℃ for 180 min. The produced samples were named as AC, CeO2–AC, and ZnO–AC, respectively. The characterization of samples was made by means of scanning electron microscope, energy dispersive spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and Brunauer–Emmett–Teller surface area. A remarkable impact on the surface, structural, and textural prope...
