Spontaneous Adsorption and Efficient Photodegradation of Indigo Carmine under Visible Light by Bismuth Oxyiodide Nanoparticles Fabricated Entirely at Room Temperature

Bismuth oxyiodide (BiOI) is a targeted material for its relative safety and photocatalytic activity under visible light. In this study, successful simple energy-saving route was applied to prepare BiOI through sonochemical process at room temperature. The characterization of the prepared conducted by physical means. transmission electron microscope (TEM) image showed that comprises nanoparticles about 20 nm. Also, surface area found be 34.03 m2 g?1 with an energy gap 1.835 eV. adsorption capacities were examined indigo carmine dye (IC) as model water-pollutant via batch experiment methodology. solution parameters optimized, including pH, contact time, IC concentration, Worth mentioning capacity 185 mg·g?1 obtained from 100 mg L?1 25 °C within 60 min equilibrium time. addition, high degradation efficiency towards tungsten lamb (80 W), where 93% removed 180 min, complete accomplished in 240 min. fabricated completely mineralized artificial light, indicated total organic carbon analysis.
