Proper　design　and　preparation　of　high-performance　and　stable　dual　functional　photocatalytic　materials　remains　a　significant　objective　of　research.　In　this　work,　highly　dispersed　Pd　nanoparticles　of　about　3-6　nm　in　diameter　are　immobilized　in　the　metal-organic　framework　(MOF)　UiO-66(NH2)　via　a　facile　one-pot　hydrothermal　method.　The　resulting　Pd@UiO-66(NH2)　nanocomposite　exhibits　an　excellent　reusable　and　higher　visible　light　photocatalytic　activity　for　reducing　Cr(VI)　compared　with　UiO-66(NH2)　owing　to　the　high　dispersion　of　Pd　nanoparticles　and　their　close　contact　with　the　matrix,　which　lead　to　the　enhanced　light　harvesting　and　more　efficient　separation　of　photogenerated　electron-hole　pairs.　More　significantly,　the　Pd@UiO-66(NH2)　could　be　used　for　simultaneous　photocatalytic　degradation　of　organic　pollutants,　like　methyl　orange　(MO)　and　methylene　blue　(MB),　and　reduction　of　Cr(VI)　with　even　further　enhanced　activity　in　the　binary　system,　which　could　be　attributed　to　the　synergetic　effect　between　photocatalytic　oxidation　and　reduction　by　individually　consuming　photogenerated　holes　and　electrons.　This　work　represents　the　first　example　of　using　the　MOFs-based　materials　as　dual　functional　photocatalyst　to　remove　different　categories　of　pollutants　simultaneously.　Our　finding　not　only　proves　great　potential　for　the　design　and　application　of　MOFs-based　materials　but　also　might　bring　light　to　new　opportunities　in　the　development　of　new　high-performance　photocatalysts.
