摘要: Abstract Magnetic BiOI/rGO/Fe3O4 composite photocatalysts were prepared by hydrothermal method and characterized XRD, FESEM, Mapping, UV–Vis DRS. Then Rhodamine B (RhB) was used as the target pollutant to investigate photocatalytic activity recyclability of magnetic photocatalysts. Results show that photocatalyst under optimum preparation conditions is slightly lower than BiOI/rGO photocatalyst, but it can be separated effectively external field, degradation rate RhB still reach 82% after 10 cycles, indicates has good recyclability.
