Synthesis of copper nanoparticle- decorated graphene oxide nanocomposite and its application in azo dye degradation



Graphene with unique physico-chemical properties is known as a new phenomenon in material science. Combining the properties of graphene with other nanomaterials, results in exceptional nanocomposites. One route is the decoration of graphene sheets with nanocrystals. On the other hand application of zero valent metals for the wastewater treatment is a widely accepted technology. In this study the nanocopper decorated graphene composite was synthesized and characterized using different methods. The possibility of its application in the degradation of 4-(2-pyridylazo) resorcinol dye was investigated. The results showed that under optimal conditions, degradation of 50 ml dye solution (100 mg L-1) with 2 g L-1 of nanocomposite is achievable.
