Analysis and study of CO 2 adsorption on UiO-66/graphene oxide composite using equilibrium modeling and ideal adsorption solution theory (IAST)

Synthesis of NiFe2O4@AC/UiO‐66(Zr) for Enhancement of the Photocatalytic Performance of Alizarin Yellow R Under Visible‐light

“…Besides, the C−O−C′s asymmetric and symmetric stretching frequencies can be observed at 1577 cm −1 and 1395 cm −1 , respectively. The vibrational band at 1585 cm −1 corresponds to the stretching C=C vibration of the benzene ring of TPA [33] . Additionally, The band observed around 1655 cm −1 is assigned to the asymmetric stretching of C=O of the DMF solvent [34] .…”

Gas separation with mixed matrix membranes obtained from MOF UiO-66-graphite oxide hybrids

“…The latter is of particular importance in the case of the CO 2 /CH 4 separation where the selectivity increased with the permeability, passing through a maximum, when the filler content was augmented (see Figure 5b). Both CO 2 diffusion (the CO 2 and CH 4 kinetic diameters are 0.33 nm and 0.38 nm, respectively) and adsorption were favored with the efficient action of the MOF well dispersed due to its synthesis on the GO sheets [28,29]. Figures S5 and S6) were analyzed with the Arrhenius equation:…”

“…While several works have addressed the preparation and application of graphene oxide [22,23], UiO-66 [16,24] and MOF-GO hybrid [25][26][27] MMMs, there are no reports on MMMs containing the UiO-66-GO hybrid as a filler. The MMMs are used in the present study to separate H 2 /CH 4 and CO 2 /CH 4 mixtures, in line with two recent publications which reveal the importance of UiO-66-GO hybrids in CO 2 adsorption [28,29].…”

Enhancing the gas adsorption capacities of UiO-66 by nanographite addition

“…This is expected to create either an interface or defects in the MOF phase and, as a consequence, to increase the porosity. Although composites containing UiO-66 and graphite oxide have been synthesized and used as CO 2 adsorbents, resulting in an increased storage capacity [17,18], their mechanism of formation was different than that expected here due to the lack of oxygen groups on nanographite used in our approach. These defects can be either of chemical or physical in nature and their geometric dimensions should be rather small and of the order of the fraction of a nanometer.…”

“…The synthesis of this MOF is relatively easy and enables the tunability of its structural defects [4][5][6][7][8][9][10]. These defects, besides being known to increase pore volumes and surface areas, also change pores' morphology/distribution and affect the adsorption of gases such as CO 2 [14][15][16][17][18], H 2 O [19,20], H 2 [15,[21][22][23], C 2 H 6 [24][25][26][27] or C 2 H 4 [25].…”
