This study aimed to synthesize a multicationic hydrotalcite and transform it into mixed oxide nanostructures (ZnO/TiO2/CeO2/Al2O3, referred as MixO) serve heterogeneous photocatalyst for degrading various pollutants, including methylene blue (MB), methyl orange (MO), paracetamol (PA), paraquat (PQ). The was synthesized via an ultrasound-assisted method calcined at 700 °C obtain the corresponding metal oxide. A comprehensive characterization of both (MC-LDH) oxides (MixO) performed using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), photoelectron (XPS), N2 adsorption–desorption, Fourier infrared (FTIR), Raman spectroscopy, pHPZC analysis. MixO sample exhibited optical bandgap 3.19 eV. Photocatalytic performance evaluated during 240 min UV irradiation, demonstrating high degradation efficiencies attributable synergistic interactions among ZnO, TiO2, CeO2. Degradation reached 99.3% MO 95.2% MB, while PA PQ showed moderate rates 60% 15%, respectively. kinetics all pollutant compounds followed Langmuir–Hinshelwood model. Additionally, catalyst maintained consistent over four consecutive cycles, highlighting its reusability stability. These findings underscore potential practical recyclable photocatalysts environmental remediation, particularly in wastewater treatment applications.
