In this work, preparation of ZIF-8 supported BiFeO3 photocatalyst by ultrasound cavitation technique was reported. The synthesized materials were characterized using solid UV absorption spectroscopy, Raman Spectroscopy, and SEM. The catalytic function of synthesized photocatalyst under ultraviolet and visible light was examined for the decolourization of Rhodamine-B (Rh-B) dye. To understand the action of the photocatalyst on Rh-B decolorization, the influence of different operating parameters such as wt% of ZIF-8 in composite, catalyst dosage, initial dye concentration, initial solution pH, and source of light was examined. The obtained results show that 40.7 wt% of ZIF-8/BiFeO3 composite exhibited the highest possible photocatalytic behaviour against decolorization of Rh-B dye. The acidic pH of the solution had shown greater effectiveness in removing Rh-B dye. The tests and study demonstrate that the hybrid ZIF-8/BiFeO3 has a stronger photocatalytic activity for decolorization of the Rh-B dye relative to the ZIF-8 MOF and BiFeO3. The synthesized ZIF-8/BiFeO3 demonstrated outstanding photocatalytic behaviour in the presence of ultraviolet and visible light towards the removal of Rh-B dye from the aqueous media.
