About this deal

G. Férey, C. Mellot-Draznieks, C. Serre, F. Millange, J. Dutour, S. Surblé and I. Margiolaki, A Chromium Terephthalate-Based Solid with Unusually Large Pore Volumes and Surface Area, Science, 2005, 309, 2040–2042, DOI: 10.1126/science.1116275. An aqueous spray-drying synthesis of the Zn-imidazole ZIF-8 was done by Tanaka et al. 134 In a typical synthesis, an aqueous suspension containing Zn-acetate and 2-methylimidazole was spray-dried at T in = 150 °C and a feed rate of 5 mL min −1. These conditions yielded dense spherical particles with an average size of 3.9 μm as confirmed by SEM and TEM. However, the XRD results suggested the formation of an unknown phase different from that of the original ZIF-8. Moreover, the product poorly adsorbed nitrogen as revealed by N 2 sorption measurements. Notably, the authors observed the coordination of dissolved species and therefore the solution turning into a suspension right before spraying. The authors explained this phenomenon as due to the hindrance of crystallization created by acetic acid, a by-product originating from the Zn-precursor. The presence of the acid in the as-synthesized product was demonstrated by means of FTIR spectroscopy and TGA. Accordingly, during the spray-drying process, the as-released acetic acid caused a rearrangement of Zn-(2-methylimidazole) bonds, leading to the amorphization of the final product due to the incomplete coordination of the ligands around the metal. Interestingly, the presence of non-coordinated ligands was similarly evidenced by TGA. However, redispersing the spray-dried particles in an alcohol enabled the recrystallization and thus the formation of the targeted ZIF-8 framework. Interestingly, the size of the alcohol molecule influenced the size of the nanocrystals: specifically, the longer the carbon chain the larger the nanocrystals. However, the microbead size remained in the same range. Upon recrystallization, the product yielded an XRD pattern characteristic of ZIF-8 with a S BET of 1440 m 2 g −1, which is consistent with the results published elsewhere. 135 Surprisingly, once these ZIF-8 microbeads were redispersed in an alcoholic solution, they undergo a transition from dense to hollow superstructures. Hence, the recrystallization process is fed by gradually dissolving the amorphous by-product from the surface to the core of the microbeads.

The latter revealed identical isotherm shapes for both the powder and extrudates. This suggests that the intrinsic hydrophilicity/hydrophobicity balance of HKUST-1 was not altered upon shaping. Besides, CO 2 adsorption experiments at 25 °C revealed gravimetric uptakes of 218 and 129 mg g −1 for the MOF in powder and extruded forms, respectively. The decrease of CO 2 uptake demonstrated by the latter is in agreement with the loss in specific surface area upon extrusion. Z. Jia, H. Li, Z. Yu, P. Wang and X.

Under the same conditions, the UiO-66 framework proved to be more stable toward high pressures. 47 Upon compression up to 69 MPa, the BET surface area of the pellet reached 1080 m 2 g −1, which is identical to that of the parent powder. Therefore, when tested for octane adsorption, the UiO-66 pellet compressed at ∼69 MPa demonstrated a saturation loading comparable to its powder counterpart (2.1 vs. 2.5 mmol g −1, respectively). A further study done by Boix et al. 143 in Maspoch's group led to the incorporation of inorganic nanoparticles into UiO-66 microbeads. The process followed the same sequence of steps, including the formation of primary nuclei in the flow reactor at 115 °C with a feed rate of 2.4 mL min −1, an inlet temperature of 180 °C, and a flow rate of 336 mL min −1. The thus-formed UiO-66 microbeads exhibited an average size of 1.5 ± 1.0 μm with a crystalline framework corresponding to the UiO-66. Additionally, the beads had a high surface area ( S BET = 945 m 2 g −1), which was slightly below than the one obtained by Garzon-Tovar et al. ( S BET = 1106 m 2 g −1) 138 following the same method. The difference might be attributed to the Zr-source used in each case: zirconium propoxide and zirconium tetrachloride, respectively. Interestingly, the UiO-66 itself was shown to be active towards the adsorption of toxic heavy metals such as Cr( VI) and As( V) with removal efficiencies of 99 and 45%, respectively. However, once functionalized with thiol (–SH) groups and doped with CeO 2 nanoparticles, it became active and efficient towards heavier metal species including Cd( II), Cu( II), Pb( II) and Hg( II) with removal efficiencies of 87, 99, 99 and 98%, respectively. Importantly, CeO 2-doped UiO-66-(SH) 2 microbeads retained their removal efficiency after 10 adsorption/desorption cycles in a continuous flow column, making them appropriate for further developments as water-purifying adsorbents.Z.

Along with the title, winners receive a medal and state diploma. Jean-Philippe Dacquin obtained his PhD from the Université Sciences et Technologies de Lille 1 (France) in 2008. After two postdoctoral years at the Cardiff Catalysis Institute following the University of York with Karen Wilson and Adam F. Lee, he returned to the University of Lille where he holds a position of Associate Professor. He's the administrative head of the bachelor of Chemistry and teaches courses on inorganic chemistry and analytical chemistry. His research is devoted to the preparation of solid catalysts with controlled porosity and their application in environmental catalysis. Peterson et al. 47 performed another study on HKUST-1 to examine the evolution of its physical and chemical properties. Thus, the authors applied pressures of 1000 psi (∼7 MPa) and 10 000 psi (∼69 MPa). While the crystal structure was globally preserved, compressed HKUST-1 exhibited broader reflections as well as high signal-to-noise ratios on the XRD patterns. This suggests partial framework damage. Consequently, there was a certain decrease in BET surface area, from 1698 m 2 g −1 for the powder to 892 m 2 g −1 for the pellets made at ∼69 MPa. These values are somewhat different from the ones reported by Kim et al., 48 who stated that above 10 MPa the HKUST-1 framework underwent structural degradation. At the same time, Dhainaut et al. 49 reported a low (15%) loss in BET surface area for HKUST-1, reaching 1091 m 2 g −1 upon densification at 121 MPa. Besides, they showed that addition of 2 wt% of a binder (graphite) slightly improved the mechanical stability of HKUST-1 pellets without significant loss of BET surface area. They explained this relatively small loss as due to the presence of the remaining solvent within the framework, acting as a scaffold during compression, as well as the slow compression speed applied to the powder bed. Therefore, each of the shaping techniques provides unique features to the final objects in terms of size and appearance for a defined application. This review will focus on conventional shaping techniques such as granulation, pelletization, extrusion, and spray-drying and challenges associated upon formulation of MOF powders. This will also include the 3D printing method as it can be referred to as a type of extrusion with controlled deposition of the forming paste in three dimensions in space. Therefore, 3D printing allows shaping powders with desired shapes and dimensions for a wide variety of applications. They will be as well discussed in the corresponding section along with the challenges related to the formulation of MOF powders. Besides, a separate section will be dedicated to the so-called non-conventional techniques which include freeze granulation, ice templating and biopolymer precipitation. Membranes and coatings, and sol–gel-based monoliths have been excluded from this review on purpose as they have been recently reviewed. 19
