Özet:

Chromium(III) oxide (Cr2O3) and electroreduced graphene oxide (ERGO) nanostructures were synthesized for the first time using a one-pot electrochemical technique on a tin oxide-coated glass (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 (SILAR) technique. The characterization of synthesized nanocomposites has been carried out using XRD, FESEM, and EDS techniques. The photodegradation of methyl orange (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.
