“…hcp UiO-66 was, so far, obtained by either using a terephthalate-containing ionic liquid or poly(ethylene terephthalate) as linker or by using large amounts of hydrochloric acid or acetic acid modulators. 49,53,54,55 To the best of our knowledge there is no functionalized hcp UiO-66 known. PXRD patterns showed the transition to the hcp structure starting with the use of ~80eq HMAc in relation to ZrCl 4 (details see Section S14, ESI †).…”

“…BET surface areas of the MAcmodulated fcu MOFs with 1290-1070 m 2 /g compare well with the surface areas of unmodulated UiO-66 of 1100 m 2 /g, 52 and modulated UiO-66 ranging from 700 up to 1600 m 2 /g, 3,52,58 Also, the BET surface area of hcp UiO-66-MAc-100eq is in good accordance with the literature. 49,53,54,55 The total surface area was differentiated in the internal micropore surface area (A Int ) and the external surface area (A Ext ) by the t-plot and V-t-method ( Table 2). The external surface area refers to all non-microporous areas and includes the surface area originating from meso-and macropores, i.e pores with diameters larger than 2 nm.…”

“…The main issues of these materials remain their synthesis, generally at the gram scale, and the final price of the materials. Recently, these materials have been produced using commercial depolymerized PET as a source of organic ligands to build various MOFs, based on Zr [10,11], Cu [12], Zn [13], Cr [14,15], Al [14,16], Ga [14], and V [16], with a high purity. We have recently proposed the use of LiB waste as a source of metal ions for the synthesis of such materials [17][18][19].…”

Combining Organic and Inorganic Wastes to Form Metal–Organic Frameworks

et al. 2020

This paper reports a simple method to recycle plastic-bottle and Li-ion-battery waste in one process by forming valuable coordination polymers (metal–organic frameworks, MOFs). Poly(ethylene terephthalate) from plastic bottles was depolymerized to produce an organic ligand source (terephthalate), and Li-ion batteries were dissolved as a source of metals. By mixing both dissolution solutions together, selective precipitation of an Al-based MOF, known as MIL-53 in the literature, was observed. This material can be recovered in large quantities from waste and presents similar properties of purity and porosity to as-synthesis MIL-53. This work illustrates the opportunity to form hybrid porous materials by combining different waste streams, laying the foundations for an achievable integrated circular economy from different waste cycle treatments (for batteries and plastics).

Metal–organic frameworks (MOFs) show captivating performances in many large‐scale applications including gas adsorption and separation, heat reallocation, water production, or remediation which can overcome important drawbacks of the conventionally used porous materials in the industry. This raises, therefore, the commercial interest in MOFs which brings the necessity to decrease the cost of their production, calling for the synthesis optimization from small‐scale to large‐scale. However, the commercial availability, yet very limited, is highly dependent on their production cost. Thus, to promote the commercial development and availability of MOFs, many steps can be taken. In this work, the state‐of‐art of the large‐scale production of MOFs can be first outlined, before discussing the criteria of greener MOF synthesis processes. Besides, a critical evaluation of the available synthesis routes for large‐scale production can be given, taking into consideration their cost, environmental impact, safety, and feasibility. Moreover, since there are strong limitations to the use in the powder form, the shaping procedures can thus be discussed briefly to outline the prospects of MOFs for different industrial applications. Finally, yet importantly, the perspective for MOFs commercialization can be highlighted with an emphasis on the necessity of techno‐economic analyses and life‐cycle assessments.
