Bimetallic ternary Cobalt Bismuth Iodide for visible-light-drive N photocatalytic degradation of industrial dyes (TB)

Abstract

In the water treatment process, sustainable, easy, effective and less expensive technique is always challenging and demanding. For this perspective, metal iodide shows great efficiency towards dye degradation processes. The present work explores the degradation of toluidine blue with the help of synthesized cobalt bismuth iodide (CBI). Structural and textural features show that on the sheet of bismuth iodide, tiny particles of cobalt iodide are uniformly distributed. The effect of various parameters such as – initial pH, dye concentration, amount of cobalt bismuth iodide and exposure of light intensity were examined. The experimental results indicate that cobalt bismuth iodide is having the advantage of the photodegradation process and is considered a significant new photocatalyst. The kinetics involved in the degradation was found to follow the pseudo-first-order kinetic model. At last, we discuss possible mechanisms for the mineralization of toludine blue. This study reveals a new choice for the potential application of cobalt bismuth iodide for the degradation of organic pollutants in water streams.
