Boosting CO<sub>2</sub> adsorption and selectivity in metal–organic frameworks of MIL-96(Al) <i>via</i> second metal Ca coordination

In this study, three improved versions of UiO-66 metal organic frameworks (MOFs) were synthesised successfully: Different ratios of Ca+2/Zr+4 were used to synthesise UiO-66, UiO-66-10%Ca and UiO-66-30%Ca. Batch adsorption experiments were achieved to remove MB from wastewater by UiO-66-Ca. UiO-66-10%Ca exhibited the highest adsorption capacity with maximum MB adsorption capacity of 15 mg. g–1 in UiO-66-30%Ca while UiO-66 demonstrated lower MB loading. Langmuir and Freundlich models have been employed to describe isotherms. A kinetics study indicated pseudo first-order and pseudo second-order equations. In addition, an intraparticle diffusion model was utilised. The results presented here may facilitate the further enhancement of UiO-66 MOFs and advance the synthesis of multimetal MOFs in future research.

“…Gas adsorption and separation are the main applications of MOFs due to their large surface areas. Abid and co‐workers [61] investigated into CO 2 capture of MIL‐96(Al) and it exhibited excellent CO 2 adsorption capacity and chemical stability. This research was improved by coordinating metal Ca as the second metal of the MOF by using the hydrothermal method.…”

Nowadays, sustaining the atmosphere and protecting it from global warming are recognized as the main concerns of the planet. This problem has been addressed through the development of a number of different carbon capture and sequestration approaches. Lately, metal‐organic framework (MOF) has emerged as the most auspicious CO2 adsorption and conversion material. This novel class of porous material has demonstrated tremendous potential for gas separation technologies, particularly CO2 adsorption and conversion due to their remarkable characteristics. Therefore, the present review attempted to provide current understanding of the CO2 adsorption and conversion performance over MOF‐based materials. This review paper discussed the type and properties of the MOF, effect of metal and ligand on MOF's properties, and various applications of MOF. Furthermore, future insights were proposed for better design and development of MOF‐based materials for CO2 applications.

“…Recently, metal-organic frameworks (MOFs) have been regarded as promising materials for gas storage and separation [1][2][3][4], catalysis [5][6][7], drug delivery [8,9], sensing [10] and other application areas [11] due to their high permanent porosity, ultrahigh surface area and diverse chemical functionalities. Zeolitic-imidazolate frameworks (ZIFs) are a subclass of MOFs, in which metal ions (e.g., Co, Zn, Cu) are tetrahedrally bonded to the N atoms of imidazolate linkers [12][13][14].…”
