Photocatalytic Degradation of Tetracycline Using a Graphene-Based Composite (MoS۲/GO/ZnO)

This study assesses a synthesized heterogeneous photocatalyst for the removal of tetracycline from aqueous solutions. To enhance photocatalytic performance, a MoS۲/GO/ZnO nanocomposite was prepared by loading ZnO and MoS۲ onto a graphene substrate with oxygen functional groups and strong absorption. By increasing dispersion and surface area, along with the incorporation of ZnO and MoS۲, 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 ۸۵%) of the pollutant was achieved within ۹۰ minutes of light irradiation at pH = ۷.
