Organic dyes were prepared by dissolving them in Sol.1 with a concentration of 152 µM of MO and BB. Conducting photocatalysis in toluene is impractical because most dyes are soluble in aqueous or polar solvents. Furthermore, photocatalysis becomes unfeasible in high concentrations of EtOH due to the rapid decomposition of the HPs in such an environment. Consequently, we investigated the photocatalytic capabilities of the HPs for dye degradation in Sol. 1.
