【 摘 要 】

Gd2CoMnO6 nanostructures (GCMO NSs) were synthesized through a simple combustion method at 800 degrees C calcination temperature in the presence of the different amino acids, including phenylalanine, beta-alanine, leucine, valine and glycine, as combustion, gelling and stabilizing agents. In this work, metal nitrate salts were used as starting materials and the Gd:Co:Mn molar ratio was selected to be 2:1:1. The beta-alanine was selected as the optimum amino acid. Effects of type of the amino acid and calcination temperature on the morphology and particle size of the products were investigated. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), ultra violet-diffuse reflectance spectroscopy (UV-DRS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray (EDX) and vibrating sample magnetometer (VSM) were used for characterization and investigation of the applications of GCMO NSs. VSM results showed an antiferromagnetic behavior for the GCMO NSs. Optical properties of the NSs were investigated and the optical band gap of them was found to be 3.28 eV. Also photocatalytic properties of the GCMO NSs for the degradation of methyl violet, erythrosine and eriochrome black T were investigated. (C) 2018 Elsevier B.V. All rights reserved.
