“…CO 2 adsorption processes over zeolites [37], carbons [38], mesoporous silica [39], and MOFs [40] have been investigated for carbon capture and sequestration. It was recently reported by us that UiO-66 with coordinatively unsaturated zirconium metal sites and uniform microporosity exhibits moderate CO 2 adsorption capacity at 1 bar condition; 84 mg/g at 298 K according to the CO 2 adsorption isotherm measured under static conditions.…”

“…NH 2 -MIL-125(Ti) was selected as host material because (i) the overall MOF structure is stable in aqueous media, 43,44 (ii) the multinuclear Ti-centers are both photo-and redox-active 24,45 and (iii) recent experimental 37 and theoretical studies 46 have shown that the photochemical properties can be tuned by changing the aromatic linker. It is noteworthy that NH 2 -MIL-125(Ti) has been used for photocatalytic hydrogen production, both in the absence and presence of Pt-nanoparticles, 24 suggesting that the reduction potential of the excited states in the MOF is sufficient to drive proton reduction in line with computational predictions.…”

Co@NH2-MIL-125(Ti): Cobaloxime-derived Metal-Organic Framework-based Composite for Light-driven H2 Production Nasalevich, M.A.; Becker, R.; Ramos-Fernandez, E.V.; Castellanos, S.; Veber, S.L.; Fedin, M.V.; Kapteijn, F.; Reek, J.N.H.; van der Vlugt, J.I.; Gascon, J.

We present a synthetic strategy for the efficient encapsulation of a derivative of a well-defined cobaloxime proton reduction catalyst within a photoresponsive metal-organic framework (NH 2 -MIL-125(Ti)). The resulting hybrid system Co@MOF is demonstrated to be a robust heterogeneous composite material. Furthermore, Co@MOF is an efficient and fully recyclable noble metal-free catalyst system for lightdriven hydrogen evolution from water under visible light illumination. Broader contextThe development of new strategies for the efficient valorization of solar light is one the most important challenges we face nowadays. Among the different possibilities, dihidrogen molecule is considered as one of the possible future energy carriers allowing for CO 2 -free energy cycle. Although the photocatalytic water splitting was the rst photocatalytic reaction to be discovered, no photocatalytic systems for this reaction have been industrially applied. This is both due to the fact that most discovered catalysts rely on the use of noble metals and to the low activities achieved so far by alternative catalysts. The application in this eld of materials such as metal-organic frameworks (MOFs) can be a game changer in this research eld. MOFs have been proven to be photoactive and their optical properties can be easily tuned towards visible light operation. The current challenge lies in the development of more appropriate active sites for the desired photocatalytic cycle. In this manuscript, we report a new strategy to achieve this goal. By introducing a derivative of the well-known molecular Co-based electrocatalyst Co-dioxime-diimine into the pores of a photo-active NH 2 -MIL-125(Ti) following a 'Ship-in-a-bottle' strategy, we were able to synthesize a highly active photocatalyst composite free of noble metals, and fully recyclable. Because of the novelty and the implications of this work, we feel that it might appeal to the interdisciplinary readership of energy and environmental science. The journal has previously been an important forum for the research topics touched upon in this paper (new earth abundant materials and their application in (photo) catalysis and hydrogen evolution from water under visible light illumination). We would be glad t...

“…Some reports have appeared on the introduction of synthesis a series of functionalized MOFs containing the BDC-X ligand (X = -NH 2 , -OH, -CH 3 and -NO 2 ) [28][29][30][31][32]. For instance, Kim et al [33] have studied that NH 2 -MIL-125 showed a higher catalytic activity and significantly superior CO 2 adsorption capacity than MIL-125. Recently, Liang et al [34] realized for the first time the photocatalytic reduction of Cr(VI) to Cr(III) under visible light irradiation over a photoactive Incontaining MOF [MIL-68(In)-NH 2 ].…”

In this paper, metal-organic framework NH 2 -MIL-101(Cr) was prepared and used as an adsorbent for removing tetracycline from aqueous system. The results showed that NH 2 -MIL-101(Cr) had the better adsorption property for tetracycline. The adsorption capacities for tetracycline reached 36.15 and 48.80 % in 10 and 240 min, respectively. Additionally, the study of adsorption kinetics and thermodynamic theories showed that the adsorption kinetics and thermodynamic datum of tetracycline were adapted to the pseudo-second-order model and the Freundlich model, respectively. In the meantime, the adsorption process was considered as an endothermic process, spontaneous nature of the adsorption and chemical adsorption in dominating station.
