Abstract
Visible light active graphitic carbon nitride/reduced graphene oxide/silver oxide nanocomposites with a p-n heterojunction structure
were synthesized by chemical deposition methods. Prepared samples were characterized by XRD, FTIR, SEM, TEM and DRS.
Photocatalytic activity investigated by analyzing the Acid blue 92 (AB92) concentration during the time under visible light.
Effects of pH, dye concentration, photocatalyst dosage, and different scavengers on photocatalytic performance were explored.
Maximum photocatalytic degradation was observed at pH = 7. Among different scavengers, silver nitrate demonstrated the maximum
activity for dye degradation. Photocatalyst with 400 ppm concentration showed the highest activity. Proposed mechanism and reaction
kinetics were also discussed.
