| Abstract: | The photocatalytic process of BiFeO3 disks under visible light irradiation can be termed as photo-Fenton-like reaction. The active hydroxyl radicals (•OH) generated during the photocatalytic process were quantified using a terephthalic acid (TA) fluorescence probing technique, which were proved to be greatly influenced by the loading of H2O2 and catalyst dosage. Our results showed that the photocatalytic efficiency was enhanced with the increasing •OH concentration. There is an optimal loading of H2O2 (80 mM) and catalyst dosage (2.0 g/L), at which the photocatalytic degradation rate of MO was enhanced to 97% under visible light irradiation for 3 h. |
