ZnO/Ag solution has been successfully prepared using the sol-gel method. The coating of the material has been carried out on a glass substrate by the spray coating method. The deposition has been successfully carried out on a glass substrate. A perfectly deposited ZnO/Ag thin film has been obtained. Seeing the photocatalytic properties of the ZnO/Ag thin film to decompose the Malachite Green (M.G) pollutant is the aim of this research. ZnO/Ag thin film will increase the contact area between ZnO/Ag thin film and the polluted solution. Materials were characterized using XRD for phase analysis. Bond vibration analysis was tested by FTIR. SEM test to see the morphology of the ZnO/Ag thin film. Optic properties test is also carried out to determine the transmittance and absorbance of the material. The use of a solar simulator is very interesting as a light source used for photocatalytic testing of ZnO/Ag thin films against Malachite Green. Then, analysis of the results of photodegradation of dye waste using solar simulator test. The photodegradation test was carried out at 10 ppm M.G for 120 minutes. The result of photodegradation using ZnO thin films are 46%. Then photodegradation was also carried out using ZnO/Ag thin films are 55 %. Reuse the same ZnO/Ag thin films are 88 %. This research can be developed further. Because, in addition to its great potential, thin film can reuse with the same or even better performance. © 2023 Author(s).
