Fine-tuning the dye adsorption capacity of UiO-66 by a mixed-ligand approach.

The mixed ligand synthetic approach offers an alternative to engineering a specific character in metal-organic framework (MOFs) materials. Herein, we synthesized and characterized a well-known prototype zirconium-based-MOF, so-called UiO-66, and its mixed ligand derivatives UiO-66-xATA, where x is mole fraction (0.5, 0.

Effect of Co(II) dopant on the removal of Methylene Blue by a dense copper terephthalate.

In this research, for the first time, a series of Co(II) doped copper terephthalate (CoX-CuBDC, where X is doping percentage) were successfully synthesized via solvothermal method and were tested for dye removal application. The physical properties of CoX-CuBDC were studied by several techniques including X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy-dispersive spectroscopy (EDS), thermogravimetric analysis (TGA) and Brunauer-Emmett-Teller (BET) surface area analysis. The incorporation of Co(II) dopant leads to isomorphic substitution of Cu(II) in the CuBDC framework with the maximum doping percentage of 22.
