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

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.
