Design of Bi۲O۳ Coupled Potassium Bismuth Oxide Iodide Nanophotocatalyst via Microwave -Combustion Manner for Outstanding Solar -Light Driven Elimination of Dye Effluent

The study focused on treating synthetic effluent contaminated with crystal violet dye by utilizing a Bi۲O۳-KBi ۶O۹I nano photocatalyst, which was synthesized through the microwave-combustion method using sorbitol as the fuel. Characterization of the nano photocatalyst was carried out using X-ray diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM) techniques. The XRD analysis confirmed the formation of the desired phases, and the FESEM analysis also demonstrated the sample's morphology as a porous material. The effectiveness of the prepared nano photocatalyst was evaluated under simulated solar light for degrading ۵ mg/L of crystal violet dye. The results indicated that with ۲ g/L of Bi۲O۳-KBi ۶O۹I, a notable degradation of ۹۹.۶% was achieved after ۱۵۰ minutes irradiation. This could be concluded from the appropriate heterojunction formation, unique morphology and effective light harvesting.
