摘要

This study explores the potential of Ce-ZnO nanospheres for degrading organic pollutants in water, focusing on enhancing photocatalytic efficiency (PE) through cerium (Ce) doping. X-ray diffraction (XRD) confirmed the wurtzite-hexagonal ZnO phase with minor CeO2 peaks, indicating successful doping. Increasing Ce concentration reduced diffraction peak intensity. The nanoparticles were spherical (~65 nm), with an average crystallite size of 71 nm. Ultraviolet–visible spectroscopy revealed a 0.25 eV bandgap reduction in doped ZnO, enhancing visible light absorption. Fourier transform infrared (FTIR) spectroscopy showed a slight shift in the Zn–O band, with no detectable cerium-related bonds. Among the samples, 3% Ce:ZnO exhibited the highest photocatalytic activity. Density functional theory (DFT) calculations supported the experimental results, confirming Ce doping as an effective approach for improving ZnO photocatalytic performance in environmental applications.
