Synthesis, characterization and photocatalytic properties of nanoparticles CuAl2O4 by Pechini method using Taguchi statistical design

摘要

In the present work nano crystalline copper aluminate (CuAl2O4) has been synthesized by the Pechini method using aqueous solutions containing corresponding metal nitrates. A Taguchi L4 statistical design was employed for investigating the most effective factors on the synthesis conditions and their interactions and production optimization. Nano crystalline CuAl2O4 particles with crystal size between 17 and 26 nm were obtained. The product characterized by XRD, FT-IR, DLS and TGA. The morphological properties have investigated using SEM. The photocatalytic degradation was investigated using methyl orange under the irradiation of visible light.
