摘要：

In the present study, Sr2TiO4 nanostructutes were synthesized by a sono-chemical method. The influence of the alkaline agent on the shape and particle size has been investigated. These alkaline agents were different from each other in the number of amine groups. These amines affected the morphology of the product and optimizing was done according to scanning electron microscopy (SEM) images. Products were also characterized by X-ray diffraction (XRD), N-2 adsorption (BET), Fourier transform infrared (FT-IR), transmission electron microscopy (TEM), X-ray energy dispersive spectroscopy (EDS) and Ultraviolet visible absorption (UV-vis) spectroscopy. The photocatalytic activity was studied for degradation of azo dyes as models of chemical contaminants. The effect of morphology and type of azo dyes on degradation efficiency was investigated. Results show that the best catalytic activity was observed for nanoparticles that synthesized in the presence of ethylene diamine. (C) 2016 Published by Elsevier B.V.
