“…The same degradations were also recently reported at room temperature after 1 year exposure to the atmosphere takes place over longer periods of time. The same structure's degradation has been observed recently when HKUST-1 was naturally stored at room temperature for a year [55]. A re-crystallisation method (using synthesis media, ethanol or ethanol/water mixture) was also proposed for the reconstruction of HKUST-1.…”

“…However, a large amount of EtOH is still required to purify and activate the products. 17,[20][21][22][23] The mechanical impact process also encounter the risk of serious explosion. From a commercial and sustainable viewpoint, using cheap and recyclable solvent and maximally reducing waste liquid to save processing energy should be taken into consideration.…”

To prepare more and better metal organic frameworks (MOFs) from less solvent for capturing greenhouse gas, a modified slurry crystallization (MSC) method has been first demonstrated for making MOF copper 1, 3, 5-benzenetricarboxylate from a solvent-deficient system. One outstanding advantage is its drastic reduction of solvent consumption and waste liquid in the whole synthesis. In a typical process, the mass ratio of ethanol to the solid reactants is ~ 0.52, which is only about 0.35% ~ 7.5% of that used in conventional processes. A high yield of ~ 98.0 % is easily achieved for the product with uniform size up to 160 μm. The obtained MOFs demonstrate the characteristic microporous network with a surface area of ~1851 m 2 g −1 and a pore volume of ~0.78 cm 3 g −1 , which benefit to adsorb high quantity of CO2 ~ 6.73 mol kg-1 at ordinary pressure. X-ray diffraction studies indicate that the MOFs possess an outstanding diffraction intensity ratio of the crystal plane (2, 2, 2) to (2, 0, 0), I(222)/I(200) = 22.4. The MSC method provides a cost-effective approach for large-scale production of MOFs with more attractive properties than others. Most importantly, it can significantly cut down the waste liquid and production cost.

“…Although Zr-MOF digestion has been studied in aqueous solution with strong acids or corrosive or oxidizing reagents (i.e., HCl, HNO 3 , HF, and CeF) [32][33][34][35] , they are difficult to thoroughly dissolve even under such harsh conditions, which restricts their practical applications. Meanwhile, the regeneration of MOFs may offer access to cost-efficient and eco-friendly applications, but only few MOFs (such as MOF-5 and HKUST-1) have been investigated [36][37][38] . Furthermore, the structures of these regenerated MOFs are unstable in moisture.…”

The digestion/regeneration of metal-organic frameworks (MOFs) has important applications for catalysis, drug delivery, environmental decontamination, and energy storage, among other applications. However, research in this direction is limited and very challenging. Here, we develop a facile method to digest and regenerate a series of zirconium-based metal-organic frameworks (Zr-MOFs) by bicarbonate or carbonate salts. As an example, UiO-66 demonstrates well the mechanism of reversible digestion/regeneration processes. By analyzing the digested zirconium species via X-ray diffraction, Fourier transform infrared spectroscopy and Raman scattering spectroscopy, a digestion mechanism based on the formation of dissoluble complexes [Zr 2 (OH) 2 (CO 3) 4 ] 2− is proposed. Impressively, ultrafine Pd nanoparticles can be extracted from Pd@PCN-224 via this strategy. This work, thus, may provide new insight for the development of renewable MOFs and their practical applications.
