dc.description.abstract | Inspired by the effectiveness of cyclodextrin (CD) auxiliary agents in the design of nanocomposite materials, we hypothesized that the same approach can be employed in the controlled assembly of zirconium-based metal–organic frameworks (Zr-MOFs) of the UiO-66-X topology, in aqueous media. Native CDs (α-CD, β-CD and γ-CD) in different proportions were initially applied as co-modulators to the reaction mixture of the Zr6O4(OH)4(CH3COO)12 cluster zirconium precursor and the 2-aminoterephtalic acid linker, to assess their influence on the porous properties of the Zr-MOFs. Crystallinity and textural characteristics of the so-obtained materials were determined by means of X-ray diffraction and N2-sorption analysis. Even at low concentrations, γ-CD was shown to have a deleterious effect on the Zr-MOFs' specific surface area and their overall N2 sorption properties. Conversely, α-CD and β-CD aided synthesis of Zr-MOFs resulted in superior textural properties outperforming those obtained with classical hydrothermal syntheses, yielding a record surface area of SBET = 1451 m2 g−1, suggesting that these co-modulators efficiently participate in the growth of UiO-66-NH2. This effect is hereby rationalized through the different roles played by the CDs towards the reagents in the UiO-66-NH2 reaction mixture, and a reaction mechanism is proposed. | en_US |
