N-Quaternization of pyridine sites in UiO-67-bpy affords a cationic MOF UiO-67-bpy-Me with faster and improved anionic dye and CO2adsorption, and extended visible-light absorption properties, which make UiO-67-bpy-Me more efficient in photodegrading organic dyes.
The magnetic CoFe2O4/MIL-101 (Cr) metal–organic framework nanocomposite containing P2W18O626− polyoxometalate was fabricated and applied as an ultrafast adsorbent to remove organic dyes from water.
