Abstract
The photocatalytic degradation efficiency of CoTiO3 coupled Sr, N codoped TiO2 has been examined by the degradation of Reactive Yellow 84 (RY 84) under solar light irradiation. The efficient CoTiO3/Sr, N codoped TiO2 based heterojunction composite was prepared via dispersed method and the results were compared with Sr, N codoped TiO2 and bare TiO2. The prepared photocatalysts were analyzed by x-ray diffraction [XRD], scanning electron microscopy [SEM] and diffused reflectance spectroscopy [UV-DRS] and Photoluminescence study [PL] , which implies the crystal structure, surface morphology, optical properties and quenching of electron role recombination. The charge separation of CoTiO3/Sr, N codoped TiO2 heterojunction composite has been improved as a result of coupling CoTiO3 and Sr, N codoped TiO2 with different energy levels and the responsible for the enhancement in the rate of photocatalytic degradation. The CoTiO3/Sr, N codoped TiO2 heterojunction composite shows better photostability at continuous photocatalytic runs. Our report will helps in the establishment and development of photocatalytic research.
