In　this　work,　CdS　quantum　dots　(QDs)　were　planted　on　magnetically　recyclable　porous　Fe2O3　(denoted　as　F450)　to　obtain　CdS　QDs/porous　Fe2O3　hybrids　(denoted　as　X–CdS/F450,　in　which　X　is　the　immersion　times　of　CdS　QDs).　Porous　Fe2O3　was　first　obtained　by　pyrolysis　from　an　iron-containing　metal–organic　framework　by　a　two-step　calcination　method.　Next,　CdS　QDs　(of　average　size　3.0　nm)　were　uniformly　and　closely　attached　to　the　porous　F450　via　a　sequential　chemical-bath　deposition　strategy.　As　expected,　the　X–CdS/F450　hybrids　serve　as　high-performance　photocatalysts　for　the　degradation　of　bisphenol　A,　a　typical　endocrine-disrupting　chemical.　Almost　∼100%　of　the　bisphenol　A　was　degraded　over　5-CdS/F450　after　visible　light　irradiation　for　30　min　(λ　≥　420　nm).　In　comparison,　the　degradation　efficiency　of　pure　F450　powder　is　59.2%.　The　high　performance　of　5-CdS/F450　may　be　ascribable　to　the　fast　electron　transport　of　porous　F450,　the　intense　visible-light　absorption　of　the　CdS　QDs　and　the　matched　energy　levels　between　CdS　and　F450.　More　significantly,　through　the　photocatalytic　degradation　reaction,　the　X–CdS/F450　hybrids　can　easily　be　recovered　magnetically　and　reused　in　subsequent　cycles,　indicating　their　stability　and　recyclability.　©　2020　by　the　authors.　Licensee　MDPI,　Basel,　Switzerland.
