“UTSA-16 (UTSA = University of Texas at San Antonio) is another MOF with the empirical formula K2Co3(C6H4O7)2, and it is characterized by a large proportion of open metal sites. Its advantages include excellent adsorption capacity for the capture and removal of CO2 with high selectivity at ambient conditions with a relatively simple recovery step, remarkable volumetric capacity, as well as the employment of cheap raw materials for its synthesis involving affordable precursors and nontoxic solvents, which in economic terms can facilitate the scaling up of the synthesis. Moreover, it is quite stable in the presence of water [26]. UTSA-16 is a selective adsorbent for CO2 capture and purification of H2, and it has raised interest due to its magnetic properties, and a composite of UTSA-16 and graphene oxide is used for biogas decarburization [27,28,29]. Thermal stability is cited as one of the disadvantages of UTSA-16 that could be improved by forming composites, such as with graphene oxide [30].”
