“…[21] After further activation at 150 8C, the XRD patterns of the MIL-53 AlOH and MIL-53 BM samples are in agreement with the calculated MIL-53(Al)lt (low-temperature) phase, and the XRD pattern of MIL-53 AlO matches the calculated MIL-53(Al)ht (high temperature) phase [16] (Supporting Information, Figure S1), thus revealing the successful conversion of the selected aluminum sources into MIL-53(Al). Among the MIL-53(Al) products derived from the four aluminum sources, MIL-53 BM presents the sharpest diffraction peaks and thus the highest degree of crystallinity.…”

“…[15] Commercially produced by BASF (Basolite A100), [16] MIL-53(Al) possesses a reversible structure that arises from the breathing effect and excellent thermal, moisture, and chemical stabilities. MIL-53(Al) was hydrothermally fabricated from Al(NO 3 ) 3 ·9 H 2 O as the metal source and 1,4-benzenedicarboxylate (H 2 BDC) as the organic linker at 220 8C for 3 days.…”

Three aluminum compounds, namely alumina, aluminum hydroxide, and boehmite, are probed as the metal sources for the hydrothermal synthesis of a typical metal-organic framework MIL-53(Al). The process exhibits enhanced synthetic efficiency without the generation of strongly acidic byproducts. The time-course monitoring of conversion from different aluminum sources into MIL-53(Al) is achieved by multiple characterization that reveals a similar but differentiated crystallinity, porosity, and morphology relative to typical MIL-53(Al) prepared from water-soluble aluminum salts. Moreover, the prepared MIL-53(Al) constructed with the three insoluble aluminum sources exhibit an improved thermal stability of up to nearly 600 °C and enhanced yields. Alumina and boehmite are more preferable than aluminum hydroxide in terms of product porosity, yield, and reaction time. The adsorption performances of a typical environmental endocrine disruptor, dimethyl phthalate, on the prepared MIL-53(Al) samples are also investigated. The improved structural stability of MIL-53(Al) prepared from these alternative aluminum sources enables double-enhanced adsorption performance (up to 206 mg g(-1)) relative to the conventionally obtained MIL-53(Al).

“…All these values easily surpass those of conventional solvothermal synthesis methods on the laboratory scale (C-ZIF-8, 3.9 kg m -3 d -1 ) and commercial ZIF-8 (Basolite Z1200, 100 kg m -3 d -1 ) [45], and are three times higher than the highest STY reported for C-ZIF-8 synthesized by the aerosol method (3875 kg m -3 d -1 ) [48]. The STY of hierarchical porous ZIF-8_C1 (up to 1.29×10 4 kg m -3 d -1 ) is a new record, which is comparable to those of Al-based MOFs that are currently produced on the ton-scale [49]. Although the STYs vary for the different organic amines, these values remain high, indicating that scale-up of the rapid room-temperature synthesis of hierarchical porous ZIFs to an industrial level is feasible.…”

Hierarchical porous zeolitic imidazolate frameworks (ZIFs) have potential for adsorption, catalysis and chemical sensing applications. Ultrafast synthesis of ZIFs at room temperature and pressure is particularly desirable for large-scale industrial production. Here, we developed a green and versatile method using organic amines as supramolecular templates (organic amine-template) to rapidly synthesize hierarchical porous ZIFs (ZIF-8, ZIF-61 and ZIF-90) at room temperature and pressure. The synthesis time was reduced dramatically to within 1 min, and the resulting ZIFs had multimodal hierarchical porous structures with mesopores/ macropores interconnected with micropores. Notably, the space-time yield (STY) of hierarchical porous ZIF-8 was up to 1.29×10 4 kg m -3 d -1 , which is more than three times higher than that reported using other methods. Furthermore, the morphologies and porosities of the produced ZIFs could be readily tuned by controlling the synthesis time or type of organic amine. The organic amine played two roles in the synthesis: (1) a protonation agent to deprotonate organic ligands, facilitating the formation of ZIF crystals, and (2) an structure directing agent to direct mesopore/macropore formation. The resulting hierarchical porous ZIF-8 exhibited enhanced uptake capacities and diffusion rates for guest molecules relative to its microporous counterpart. This work provides a new direction for the green and efficient synthesis of various hierarchical porous ZIFs with high STYs for a wide range of applications.

“…One major limitation to using MOFs is that only small quantities, usually <1 g per batch, of the active material can be synthesized although production of a MOF material at an industrial scale has been reported. [ 57 ] Moreover, probably the least considered factor, the environmental impacts of MOFs cannot be ignored, particularly if they are to be used on an industrial scale. Many MOF systems are built using toxic transition metals (Co, Ni, Mn, Cu) and ligands (aromatic and/or heterocyclic compounds) and these materials may cause serious environmental issues upon disposal.…”

Carbon capture and storage (CCS) technologies aiming at tackling CO2 emission have attracted much attention from scientists of various backgrounds. Most CCS systems require an efficient adsorbent to remove CO2 from sources such as fossil fuels (pre‐combustion) or flue gas from power generation (post‐combustion). Research on developing efficient adsorbents with a substantial capacity, good stability and recyclability has grown rapidly in the past decade. Because of their high surface area, highly porous structure, and high stability, various nanoporous materials have been viewed as good candidates for this challenging task. Here, recent developments in several classes of nanoporous materials, such as zeolites, metal organic frameworks (MOFs), mesoporous silicas, carbon nanotubes, and organic cage frameworks, for CCS are examined and potential future directions for CCS technology are discussed. The main criteria for a sustainable CO2 adsorbent for industrial use are also rationalized. Moreover, catalytic transformations of CO2 to other chemical species using nanoporous catalysts and their potential for large scale carbon capture and utilization (CCU) processes are also discussed. Application of CCU technologies avoids any potential hazard associated with CO2 reservoirs and allows possible recovery of some running cost for CO2 capture by manufacturing valuable chemicals.
