“…Nevertheless, in Ni50‐UTSA‐16, no obvious change in particle size is noted probably related to some crystal agglomeration occurring in the synthesis process . The morphology of both Ni20‐UTSA‐16 and Ni50‐UTSA‐16 materials remained unchanged compared to the parent UTSA‐16 which is in good agreement with the SEM micrographs reported in the literature . The crystallite sizes summarized in Table properly verify the observed changes of the particles in SEM images, as can be seen in Figure .…”

An open metal site framework named UTSA-16 was synthesized and modified as a high-capacity adsorbent for reversible CO 2 capture. Partial substitution of intrinsic Co 2+ sites of UTSA-16 with Ni 2+ centres was realized in the molar composition range 0-75% Ni with the aim of increasing CO 2 uptake. Synthesized bimetallic Nix-UTSA-16 (x = 0, 20, 50, 75) materials were characterized using various techniques to assess the influence of chemical composition on CO 2 binding affinity and any subsequent physical change in morphology, crystal size and porosity on the total uptake. Experimental isotherm adsorption studies showed the following trend for CO 2 adsorption capacity employing the Nix-UTSA-16 series: Ni20-UTSA-16 > UTSA-16 > Ni50-UTSA-16 > Ni75-UTSA-16. According to the dynamic breakthrough CO 2 profiles measured for a mixture of CO 2 and CH 4 (15/85 molar ratio), Ni20-UTSA-16 exhibited 2 times the breakthrough time with 1.5 times the loading capacity at 75 Nml min −1 feed flow rate, compared to the parent UTSA-16. In addition, the Ni20-UTSA-16 bimetallic metal-organic framework exhibited lower isosteric heat of adsorption compared to UTSA-16 (ΔH ave = 28.54 versus 46.85 kJ mol −1 ).As a result, more than 95% of its capacity was restored by applying a partial vacuum for only 1 h at room temperature without involving any other timeand energy-consuming regenerative step.

“…The addition of a binder and the amount can also have an impact on the material properties. 17 This paper aims to investigate three MOFs, MIL-100(Fe), Cu-BTC and CPO-27(Ni), which have been synthesised at a 1 kg scale 18 and formed in industrially relevant processes. These three materials have previously been studied 11 for ammonia adsorption within the literature.…”

The metal-organic frameworks (MOFs) MIL-100(Fe), Cu-BTC and CPO-27(Ni) were synthesised in 1 kg batches. The materials were then formed in two different industrially relevant ways. Firstly, dry granulation was used to produce pellets which were sieved to give material with a 300-1000 μm size, and the fines were subsequently recycled to mimic a large scale industrial process. Secondly, wet granulation with a polymer was used to produce granules which were again sieved to 300-1000 μm. XRD data shows that the structures of MIL-100(Fe) and CPO-27(Ni) remain intact during both forming processes, whilst Cu-BTC is shown to degrade during processing. This is in line with the ammonia adsorption data obtained for the formed materials which evaluated the ammonia adsorption capacity of the materials using breakthrough measurements. MIL-100(Fe) and CPO-27(Ni) are shown to have capacities of 47 mg g and 62 mg g respectively whilst Cu-BTC has a decreased capacity of 37 mg g from 97 mg g upon forming. The formed materials were also aged at 25 °C and 80% humidity for a week and the ammonia adsorption capacity re-evaluated. As expected, Cu-BTC decomposed under these conditions, whilst MIL-100(Fe) and CPO-27(Ni) show slightly decreased ammonia adsorption capacities of 36 mg g and 60 mg g respectively.

“…Plasticizers are additives that improve the rheological behavior of the paste for the shaping process. These materials generally include polymers such as polyethylene oxide, polyethylene glycol, polyvinyl alcohol, polyacrylamide, polyvinyl pyrrolidine, alginates, or different types of cellulose [26][27][28]. Organic plasticizers can also be used as organic binders for MOFs [29,30].…”

“…Extrusion has been established commercially to produce mechanically strong and attrition-resistant granules, pellets, and honeycomb structures of industrially important adsorbents and catalysts such as zeolites, MOFs, and porous carbon for adsorption, air separation, and catalytic applications. A schematic diagram of the extrusion process and examples of extruded bodies from zeolites are presented in Figure 18.9 [26,[60][61][62][63][64].…”

IntroductionShaping and forming of metal-organic frameworks (MOFs) are essential for practical applications like adsorption/separation and catalysis, which require structuring of the nano-/microcrystalline fine powders of MOFs into a macroscopic body [1][2][3][4][5][6][7]. When a process for catalysis or adsorptive separation is scaled up to the pilot or commercial scale, the form in which an active catalyst or adsorbent is used is decisive in determining the ultimate performance of the unit [8][9][10]. In this respect, the size and shape of the target material require a compromise between minimizing pore diffusion effects in the material particles, for which small particles are necessary, and minimizing the pressure drop across the reactor, which requires large particle sizes [11]. The shaped MOFs should maintain excellent performance shown by the original powder forms based on their high porosity, crystallinity, and flexibility [12]. Therefore, the proper selection of the shaping or forming process is important in the MOF research field for chemical engineering and industrial applications. As the shaping methods are often proprietary and often more of an art than a science, the exact procedures are rarely disclosed.The shaped MOFs can also be prepared using techniques (Figure 18.1) that have typically been utilized for synthesizing catalysts and adsorbents from porous materials, such as pressing, extrusion, granulation and spray drying, foaming, casting, and coating. Well-shaped bodies have been produced in the forms of pellets, tablets, monoliths, granules, and spheres [13][14][15][16]. However, to utilize shaped MOFs successfully for industrial applications, they should have sufficient mechanical strength, chemical stability, attrition resistance, maximal bulk density, and minimal wasted space in the storage vessel [17][18][19][20][21][22][23][24]. As the performance of shaped MOFs for industrial or large-scale applications depends on several parameters, including the mass-and heat-transfer properties, gas diffusion kinetics, pressure drop across material, mechanical strength, and volumetric efficiency, achieving high mechanical integrity of the structured MOF is critical to the performance in real engineering processes.
