Abstract

The data presented here focuses on the physicochemical characterization of perovskite CaTiO₃ nanoparticles (orthorhombic) as photocatalyts and the kinetic study of their photodegradation performance toward organic pollutant, i.e. brilliant green (BG) which is azo derivatives dye. The CaTiO₃ nanoparticles was synthesized using chicken eggshell-derived CaCO₃ and anatase TiO₂ with molar ratio of (1:1), (1:3), (2:5), and (2:7). The physical and microstructural properties of CaTiO₃ were characterized by X-ray diffractometer (XRD), scanning electron microscope (SEM), Fourier Transform Infrared (FTIR) and UV/vis spectrometer. The effect of initial dye concentration, catalyst composition, and catalyst dosage on the adsorption mechanism of dye on CaTiO₃ was investigated in jacketed photoreactor under UV irradiation. The analysis reveals that BG molecules are efficiently chemisorbed, as indicated by pseudo first order kinetic, and degraded within 120 min. Considering the low-cost preparation process and high photocatalytic performance, the resultant CaTiO₃ can further be used as an efficient photocatalyst for organic pollutant removal from aqueous and industrial wastewater.
