[Display omitted] ► Photosensitized degradation of Rodamine B was investigated on BiOX (X=Cl, Br). ► Methylene Blue could not be degraded on BiOX under visible light irradiation. ► The relationship between LOMO of dye molecules and degradation rate was established. This study reported, for the first...
