In this study, the Ag/ZnO/g-C3N4 material was prepared via a simple combustion method. The photocatalytic activity of as-synthesis material samples was evaluated by degrading tetracycline hydrochloride (TCH) in the aqueous solution. The characteristics of material samples were analyzed by the Diffuse Reflectance Ultraviolet-Visible (DR/UV-Vis), X–Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM), Energy-dispersive (EDS), and Fourier Transform Infrared Spectroscopy (FT-IR) techniques. The Ag/ZnO/g-C3N4 material had a band gap energy of 3.17 eV, lower than the ZnO nanomaterial. The Ag/ZnO/g-C3N4 material consists of spherical particles of uniform size (20-30 nm) overlapping and stacked on top of each other and has a higher photocatalytic efficiency than ZnO, g-C3N4, and ZnO/g-C3N4. The TCH degradation efficiency was achieved at 92.69 % with a rate constant of 0.022 min-1.
