Description
Summary:The crystallinity of cadmium titanate (CdTiO 3 ) was greatly improved when synthesized under mild reaction conditions, in the presence of chloride. The highly crystalline CdTiO 3 showed much enhanced photodegradation of methyl orange (MO) under simulated sunlight. CdTiO 3 was characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), N 2 adsorption/desorption, photoluminescence (PL), and UV/vis spectrometry. The enhanced photodegradation was attributed to the better charge separation owing to its higher crystallinity. The crystallinity of cadmium titanate (CdTiO 3 ) was greatly improved when synthesized under mild reaction conditions, in the presence of chloride.
