This research has successfully deposited ZnO: Ag on aluminum foil substrates with variations in deposition temperature. The purpose of this study was to obtain the surface morphology of ZnO:Ag on aluminum foil substrates with variations in deposition temperature and obtain optimization of the photocatalytic activity of ZnO: Ag in degrading Methylene Blue dyes. ZnO:Ag deposition on the aluminum foil substrate was carried out by the sol-gel method and spray coating deposition technique. Surface morphology characterization and photocatalytic activity with SEM and with UV-Vis. The surface morphology results obtained from ZnO:Ag on aluminum foil substrate with deposition temperatures of 250 ℃, 300 ℃, 350 ℃, and 400 ℃ are the forms of ganglia with indications as ZnO and Ag grains attached to ZnO. Obtained surface area and roughness level ZnO:Ag decreases with an increase in temperature from 250 ℃ - 300 ℃, and surface area and roughness increases at 350 ℃ -400 ℃. The highest level of roughness is found in the ZnO layer: Ag temperature 400 ℃. The most optimum photocatalytic activity is indicated by the largest percentage of degradation. The highest percentage of degradation is shown by the ZnO: Ag layer with a temperature of 350 ℃ of 87.33%. This is due to the modification of silver at low temperatures which is <400 ℃ effective for photocatalytic activity.
