Abstract
In this work, Nickle Bismuth Iodide nanoparticles were successfully synthesized by simple precipitation and solid-state methods. The as-synthesized photocatalyst was characterized through XRD, FESEM, EDX UV-Vis analysis. To investigate the photocatalytic activity of Nickle Bismuth Iodide, photooxidation of Azure-A and Toluidine blue was comparatively studied. The impact of several factors like pH, the concentration of Azure-A and Toluidine blue dyes, amount of Nickel Bismuth Iodide, and irradiation time were examined. Increment in the reaction rate of both dyes was monitored with the help of a spectrophotometer. A tentative mechanism has been proposed for photocatalytic decomposition of both the dyes. The experimental results show that both dyes degrade approx 85% under the visible light.
