This study assesses a synthesized heterogeneous photocatalyst for the removal of tetracycline from aqueous solutions. To enhance photocatalytic performance, a MoS2/GO/ZnO nanocomposite was prepared by loading ZnO and MoS₂ onto a graphene substrate with oxygen functional groups and strong absorption. By increasing dispersion and surface area, along with the incorporation of ZnO and MoS₂, charge transfer was improved, recombination was reduced, and a highly stable composite with enhanced photocatalytic properties was created for the degradation of tetracycline. By optimizing the pH of the tetracycline solution, nearly complete decomposition (around 85%) of the pollutant was achieved within 90 minutes of light irradiation at pH = 7
