A series of magnetic recyclable bismuth oxyiodide (BiOI)/polyacrylic anion exchange resin (PAER) composites with visible light responses have been synthesized for the first time through a facile and low-cost method at normal temperature. The photocatalytic performances of BiOI/PAER composites were evaluated by photodegrading 1-amino-8-naphthol-3,6-disulfonic acid under visible light. It was found that 1-amino-8-naphthol-3,6-disulfonic acid (H-acid) removal rate reached to 90.1% (BiOI/PAER-2), which was higher than the pure BiOI (50.3%) in 60min. The enhanced photocatalytic performance of BiOI/PAER composites should be attributed to the improved separation efficiency of the charge carriers. Furthermore, the BiOI/PAER composites exhibited excellent cyclinic utilization stability, which is a key factor for their potential practical applications.
