CHARACTERISATION OF NEXT-GENERATION SHAPED POROUS MATERIALS
Metal-organic frameworks (MOFs) are known as next-generation adsorbents and catalysts. The combination of organic and inorganic chemistry offers a virtually infinite number of possible materials that can be tailored to a vast range of different applications.

The industrial utilisation of MOFs requires that the powder is shaped into larger bodies that can be properly handled. Using inadequate shaping processes can result in undesired modifications to the original properties of the material. Testing new shaping methods, such as 3D printing, is central to assessing the fidelity of the final properties of the shaped material: MOF distribution, crystallinity and, more importantly, its adsorption properties.
The change in crystal lattice upon adsorption of CO2 in a 3D printed monolith with cobalt- MOF material, was studied by in-situ X-ray diffraction computed tomography (XRD-CT) measurements carried out at beamline ID15A using a monochromatic beam with an energy of 90 keV focused to a spot size of 40 μm × 20 μm (horizontal × vertical). The XRD-CT scans were collected using a zigzag approach over a total angular range of 180° in steps of 0.721° (i.e., 250 angular steps) combined with translational steps of 40 μm (with a total number of 320 steps across 12.8 mm) using a Pilatus3 X CdTe 2 M detector (Figure 142). The study provides a valuable example of how this methodology can be universally applied to the development of new shaped catalysts and adsorbents and optimisation of both their chemical and physical forms.
