Synthesis, Characterization, and Morphological Control of ZnTiO۳ Nanoparticles through Sol-gel Processes and Its Photocatalyst Application

چکیده مقاله

In this work, ZnTiO3 ceramics have been synthesized from the reaction of zinc acetate (Zn (CH3COO)22H2O), tetrabutyl titanate (Ti(OC4H9)4) as precursors and ethanol as the solvent, in the presence benzene-1,3,5-tricarboxylic acid as a novel chelating agent by sol-gel method. The effect of various parameters such as reaction temperature, pH effect, effect of molar ratio of benzene-1,3,5-tricarboxylic acid to tetrabutyl titanate on morphology, size and purity of products was investigated. The asprepared products were characterized by various analyses such as: X-ray diffraction (XRD), scanning and transmittance electron microscopy (SEM, TEM), X-ray energy dispersive spectroscopy (EDS), UVvis and Fourier transform infrared spectroscopy (FT-IR) technique. The photocatalytic degradation was investigated using methyl orange (MO) under ultraviolet (UV) light irradiation. Application of this product as photocatalyst was investigated through degradation of methyl orange (MO) under UV irradiation and percentage of degradation obtained about 70% after 60 min.
