Developing novel photocatalytic materials for removing organic contaminants has been a research focus. The current study reports the synthesis of third-generation photocatalysts perovskites and their photocatalytic efficacy. The lead-free cesium-based titanium halide Cs2TiI6 double perovskite was successfully synthesized via the solution processing method and characterized by various spectroscopic and morphological characterization techniques such as X-ray diffraction (XRD), UV-visible spectroscopy, Zeta potential, and Transmission Electron Microscope (TEM). The novel aspect of this study is to investigate the photocatalytic efficacy of the Cs2TiI6 double perovskite. Various morphology and spectroscopy characterization insights about synthesized photocatalysts were explored. Eosin Y (EY) and Eosin B (EB) were chosen as the model compounds for degradation in this work due to their wide applications in industry. The photocatalytic degradation efficiency of Eosin Y and Eosin B dye by Cs2TiI6 perovskite photocatalysts after exposure of 240 minutes to visible light was 85.08% and 13.66% respectively. The rate constant of degradation of Eosin Y is approximately 14.66 times larger than that of Eosin B. [ABSTRACT FROM AUTHOR] |
