“…[191] These cations were selected because of their multiple Lewis basic sites, size comparability to DMA + (pore volume does not significantly decrease after cation exchange in bio-MOF-1) and these guanidine derivatives have previously been studied as catalysts for CO2 chemical fixation. [192,193] Bio-MOF-1 and GND + @bio-MOF-1 had comparable BET surface areas and pore volumes (1630 m 2 /g, 0.70 cm 3 /g and 1640 m 2 /g, 0.70 cm 3 /g respectively). [191] The encapsulation of larger cations: AmGND + @bio-MOF-1 and DiAmGND + @bio-MOF-1 have observed that the surface areas and pore volumes decreased slightly (1600 m 2 /g, 0.68 cm 3 /g and 1500 m 2 /g, 0.66 cm 3 /g, respectively).…”

Metal organic frameworks (MOFs) are extended structures composed of a network of organic ligands and metal ions or clusters connected to each other via coordination bonds. The numerous choices of organic ligands and metal coordination geometries have led to the construction of porous MOFs with various compositions, network topologies, pore sizes and shapes and they possess high surface areas and low densities. The structures of MOFs can be tailor-tuned in such a way that any desired ligand or/and metal ion can be incorporated; this has given to researchers the advantage of designing MOFs for a targeted application. Within this review, we overview recent examples of a sub-class of MOFs namely biologically derived MOFs (bio-MOFs), made of multifunctional and commercially available biologically derived ligands (bio-ligands) such as: amino acids, peptides, nucleobases and saccharides and focus on their coordination chemistry with a variety of metals. Central to this review are four tables detailing the coordination modes of bio-ligands to metals, along with a visual representation of the bio-MOF that is subsequently formed. Through the detail analysis of these structures, we highlight the structural impact of these ligands on the structure, and their contribution to the MOFs properties and applications. Finally, we showcase the potential of bio-MOFs in several research areas such as CO2 capture, separation, catalysis, drug delivery and sensing.

“…Additionally the identity of the new bands was checked, based on available data from literature [21,26]. Moreover, and similarly to the systems without CO 2 , TMG moiety usually presents two distinctive FTIR bands in the region of 1608-1615 and 1647-1663 cm −1 associated to, at least, partially protonated TMG, another indication that reaction occurred.…”

Innovative advanced solvent based capture processes (ASBCPs) employing sophisticated separation mechanisms have emerged as essential solutions that may dramatically reduce high energy requirement of CO 2 separation in capture plants. This study systematically characterises useful mechanisms of several such ASBCPs, being mostly at relatively low technology readiness levels. Based on improved understanding of these emerging ASBCPs it is shown how they can contribute to achieving energy efficiency benefits and thus increase CO 2 capture efficiency. It is followed by an analysis of practical examples of all ASBCPs recently presented in academic and patent literature. Finally, major challenges of discussed emerging ASBCPs are identified showing potential directions for further research and development. Overall, innovative ASBCPs employ very different mechanisms translating to different energy efficiency benefits in various CO 2 capture applications. The provided technological account along with the identified challenges may be useful for capture process developers which will be able to bring the most promising ASBCPs to higher technology readiness levels and finally they can be employed in the practice.
