Abstract

Pure copper chromite nanoparticles were prepared through an efficient route using copper nitrate and chromium nitrate. For the first time, various amino acids were employed as capping agents in the presence of propylene glycol and ethylene glycol in order to prepare these nanostructures. A number of experiments were performed to examine the effect of stabilization agents, alkaline agents and connecting agents on the shape, grain size and photodegradation behavior of CuCr2O4. The results showed that the type of stabilization agent and reducing agent creates numerous changes in terms of the size and photocatalytic performance of copper chromite. The effects of several factors, including the type of pollutant, grain size of CuCr2O4 nanostructures, pH and dosage of dye, on the photocatalytic behavior of copper chromite nanostructure were evaluated. Solutions of methylene blue, methyl orange and rhodamine B were employed as model contaminants. The maximum photocatalytic activity of the CuCr2O4 nanostructure was achieved for the rhodamine B contaminant under UV irradiation. When the CuCr2O4/Ag nanostructure was used instead of CuCr2O4 nanoparticles, the photocatalytic activity during the degradation of rhodamine B increased from 76 to 91.
