450 nm visible light-induced photosensitized degradation of Rhodamine B molecules over BiOBr in aqueous solution

Abstract

A method for degrading Rhodamine B including: mixing BiOBr and Rhodamine B; and irradiating the mixture with a radiation having a wavelength of from 440 nm to 554 nm. The Rhodamine B may be in an aqueous solution. The BiOBr may be added to the aqueous solution of Rhodamine B in an amount of from 0.2 to 0.5 mg/ml. The BiOBr may have a sheet-like structure with particles having a diameter of from 3 μm to 5 μm. The BiOBr may be in a pure crystal tetragonal phase.
