Abstrakt: In this research, nano Ag/Ag3VO4/AgVO3 modified with graphene oxide as a visible-light sensitive photo catalyst was synthesized via a simple method and were investigated for the photo degradation of Reactive Orange 16 dye. The synthesized photo catalysts analyzed by XPS, XRD, FESEM, XPS, EDS, Dot Mapping, TEM, and DRS. The effect of Reactive Orange 16 dye concentration, nano Ag/Ag3VO4/AgVO3 dosage and pH on photodegradation of Reactive Orange 16 were studied in the presence of nano Ag/Ag3VO4/AgVO3 modified with graphene oxide under visible light. Results revealed that increasing of pH, dosage and dye concentration due to a decrease in the photodegradation of dye. The maximum photodegradation of Reactive Orange 16 was 97.43% in the following conditions: dye concentration = 10 mg/L; dosage = 0.1 g/100 mL; pH 6.7 under 300 W of Visible light.
