Abstract In this study, the double Z-type ternary composite MIL-88A (Fe)/Ag₃PO₄/AgI(MAI) was successfully synthesized by in-situ precipitation method and ion exchange method using MIL-88A (Fe) as the support. MAI was applied to the photo-Fenton system to efficiently remove Rhodamine B(RhB) from dye wastewater. The rod-shaped MIL-88A (Fe) was used as a carrier to reduce the agglomeration of Ag₃PO₄ and AgI particle. The formation of a double Z-type heterojunction reduced the recombination of electorn-hole pairs and improved photocatalytic activity. Under the best optimized condition of 0.5g/L catalyst, initial pH 3.0, 0.4mmol/L H₂O₂, 100mL 20mg/L RhB, RhB was completely degraded RhB within 20min. The catalyst could be maintained high catalytic property after 5cycles. In addition, free radical capture experiments and electron spin resonance experiments showed that h⁺, O₂^·﹣and HO^· were the main active substances in the MAI/Vis/H₂O₂ catalytic system. Finally, a possible mechanism for the catalysis of MAI was proposed.
