Facile synthesis and characterization of CdTiO3 nanoparticles by Pechini sol–gel method

چکیده مقاله

In this work, CdTiO3 nanoparticles were synthesized through reaction between Cd(CH3COO)2.2H2O, Ti(OC4H9)4, trimesic acid as a new chelating agent and ethanol as solvent by Pechini sol–gel method. X-ray diffraction (XRD) patterns showed that CdTiO3 nanostructures have rhombohedral structure with diameter of about 35.61 nm. The structure, morphology and size of CdTiO3 nanoparticles were characterized by FT-IR, XRD, SEM and EDAX. The optical properties of the products were studied by DRS. Based on the results of experiments, it was found that temperature and time of calcination, pH and the solvent of reaction are important parameters for formation of CdTiO3 nanoparticles. Utilizing trimesic acid (benzene-1,3,5-tricarboxylic acid) as a new chelating agent for preparation of CdTiO3 nanostructures was initiative of this work.
