Photo-Catalytic Degradation of Dyes Using Graphene Oxide–Dithizone Composite
Abstract: Graphene oxide–dithizone (GO–DTZ) composite was successfully synthesized through the copolymerization of graphene oxide and dithizone to develop an efficient photocatalytic material for wastewater treatment. The dithizone polymer was prepared using a 1:2 molar ratio, while graphene oxide was synthesized via the modified Hummers’ method to obtain highly oxidized graphene sheets with abundant oxygen-containing functional groups. The GO–DTZ nanocomposite was fabricated by ultrasonically dispersing graphene oxide with the synthesized dithizone polymer …
