Abstract :Chromiuminsert ignore into journalissuearticles values(III); oxide insert ignore into journalissuearticles values(Cr2O3); and electroreduced graphene oxide insert ignore into journalissuearticles values(ERGO); nanostructures were synthesized for the first time using a one-pot electrochemical technique on a tin oxide-coated glass insert ignore into journalissuearticles values(ITO); electrode surface. The surface of the synthesized Cr2O3/ERGO nanostructures was decorated with CdS nanoparticles by a simple successive ionic layer adsorption and reaction insert ignore into journalissuearticles values(SILAR); technique. The characterization of synthesized nanocomposites has been carried out using XRD, FESEM, and EDS techniques. The photodegradation of methyl orange insert ignore into journalissuearticles values(MO); was investigated in an aqueous suspension containing CdS/Cr2O3/ERGO catalyst under artificial sunlight irradiation. The results indicated that the modification of Cr2O3/ERGO with CdS nanoparticles exhibits a high performance for the removal of azodyes.
