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).

The MOF competition is a fierce one, requiring many months, sometimes years, of intense preparation. It aims to evaluate the dexterity, knowledge of modern and traditional techniques, know-how and creativity of candidates representing over 200 different professions, with artisans representing 16 industries as far-flung and diverse as hospitality, textiles, floral design, leatherworking, and ceramics. Within each category there are several smaller groups representing different specialties. As is evident from Table 13, both extrusion and DIW can yield shaped objects while preserving the textural properties of pristine MOFs. The loss in surface area in the case of the 3D printed objects is somewhat higher than the binder content which is due to the presence of the plasticizer. The final printed objects have a developed network of millimeter-sized channels thanks to the layer-by-layer deposition upon printing. This can significantly improve the diffusion of gas or liquid within the shaped objects. Spray-drying The spray-drying technique has been known for over a century. As the name suggests, it is used to dry powder-like materials in a continuous fashion. Compared with ovens and conveyor belts, spray-dryers allow treating several tons per hour of wet product. Over the past few decades, the application potential of spray-drying has considerably expanded and now includes the food industry, 125 the pharmaceutical industry, 126 and many others. 127

The hours of preparation, the stress of the competition, the recognition for all the work and commitment, have alla All has changed me forever. I have pushed myself beyond what I imagined possible and it certainly contributed in making me a better professional.” continues Meilleur Ouvrier de France Chef Thomas Marie The culinary connection Pelletization has been regarded for long as the “reference” technology for comparing shaping techniques. Obviously, when applying forces in the range of the ones applied industrially to zeolites and activated carbons, the MOF structures typically collapse which directly impact their final performances. However, recent developments show that when applying mild compression, along with the presence of a scaffolding compound (solvent or other), the collapsing is greatly limited. Moreover, binderless pelletization is possible owing to MOF crystals’ binding ability. Therefore, pelletization offers some of the best compromises between mechanical stability, and volumetric and gravimetric uptakes, making it a leading technique for mobility applications. To further limit the effect of compression on MOFs while reaching high mechanical resistance, isostatic compression could be advantageously used. Finally, other less-popular techniques have been successfully applied for shaping MOFs, among which have been reviewed the so-called molecular gastronomy, ice-templating (also called freeze-casting), and phase separation (also called spinodal decomposition). These three techniques presented very low impact on the physicochemical properties of the MOFs applied and are therefore worth investigating more in detail. It should be noted, however, that ice-templating and phase separation both involve the creation of a second level of porosity macrosized (>50 nm) following the replication of ice crystals and polymers, respectively. S)-2-(2′-(diphenylphosphanyl)-[1, 1′-biphenyl]-2-yl)-4-isopropyl-4,5-dihydrooxazole MOF Description Finally, Lawson et al. 111 studied the post-printing crystallization of HKUST-1 starting from a gel containing all precursors. In this case, a mixture of bentonite (21 wt%), methylcellulose (2 wt%) and PVA (6 wt%) was used to obtain satisfactory rheological properties. The as-printed grids presented a fair replication of the initial model, and they were further placed in a convection oven at 120 °C for 20 hours to induce crystallization of the MOF. The resulting material presented a S BET of 500 m 2 g −1, slightly higher than that of a comparative solid directly 3D-printed starting from the HKUST-1 powder (470 m 2 g −1). While the solids were extensively washed with acetone, residual DMF was observed by FTIR spectroscopy as characterized by a band at 2100 cm −1. Finally, the CO 2 capacities of both solids at 25 °C were compared. While the solid prepared from the HKUST-1 powder presented a CO 2 capacity 50% higher (2.1 mmol g −1 against 1.4 mmol g −1), which is not in line with their respective S BET, the solid obtained by growing HKUST-1 crystals on the as-printed solid displayed enhanced mass transfer kinetics (diffusivity × 10 8 (cm 2 s −1): 8.75 against 5.25). This was attributed to the presence of a larger extent of mesopores ( V meso (cm 3 g −1 STP) = 0.16 against 0.09).J. Alcañiz-Monge, G. Trautwein, M. Pérez-Cadenas and M. C.

Granulation is the last industrially-mature technology reviewed herein, and allows producing millimeter-sized grains. Two types of granulation techniques are typically discussed: wet granulation, when powders are aggregated in a high-shear rate mixer in the presence of a solvent; and dry granulation, when grains are obtained from a previously shaped object either mildly crushed and sieved, or spheronized. Due to higher stresses applied, the dry granulation implies more severe losses in the initial physicochemical properties of the MOFs, while the wet granulation has a less pronounced effect and therefore might be more adequate. Especially, replacing water with another solvent with a lower surface tension is highly beneficial. A. Dailly an

Moreover, spray-drying allows the direct synthesis of various materials. 128 In 2002, du Fresne von Hohenesche et al. 129 successfully prepared MCM-41 spherical microbeads with a defined arrangement of macro- and mesopores with the help of a spray-dryer. Since then, the same approach has been used for preparation of other types of porous materials, 130 allowing spray-drying to be considered as a tool for simultaneous synthesis and shaping. R.

The process parameters entirely depend on the initial powder to be shaped. Mainly, the pressure applied on it should be carefully selected to avoid the complete destruction of the crystal structure (amorphization) and therefore loss of intrinsic properties. Additionally, the rate of pressure increase should be adequate for the same reason.

S)-2-(2′-(bis (4-(trifluoromethyl)phenyl)phosphino)biphenyl-2-yl)-4-phenyl-4,5-dihydrooxazole Powder MOF Fig. 9 Schematic representation of the 3D printing process via the Direct Ink Writing (DIW) method. Bis ( (2-ethylhexyl)oxy)benzo[1,2-b 4,5-b’]dithiophene-2,6-diyl)bis (trimethylstannane) MOF Product As in the case of extrusion, the paste formulation is a crucial step in 3D printing and should yield a final composition with appropriate rheological properties. Apart from the parent powder and a liquid, the paste is also composed of a binder and a plasticizer. The former provides adequate mechanical resistance to the final 3D objects, while the latter improves the flowability and plasticity of the paste to be printed. One of the major differences is the printing nozzle: while the die in extruders can reach sizes up to a few centimeters, in 3D printers the nozzle (or needle) is typically smaller than millimeters in diameter. Such a thin nozzle allows designing objects with complex geometries that would be challenging to obtain via a conventional method. On the other hand, the CPO-27 and MIL-100 frameworks proved to be more stable under the applied conditions, as the granules’ diffractograms yielded matching patterns with their powder counterparts. The MIL-100 granules presented only a slight decrease in SSA ( S BET = 1172 m 2 g −1), which is in the range of 2% loss as compared to the parent powder ( S BET = 1212 m 2 g −1), consistent with the initial amount of the binder. Surprisingly, the CPO-27 granules exhibited a considerable increase in specific surface area ( S BET = 1319 m 2 g −1) as compared to S BET = 937 m 2 g −1 of the as-synthesized CPO-27. This phenomenon was stated to be unclear by the authors.
