“…In these porous materials, the charge (cation/anion) of the skeleton in MOFs, which has been ignored as a factor, has a strong impact on their adsorption function. The counterions usually occupy the void space, which potentially allows dyes with opposite charge to enter into the pores of the skeleton in MOFs through ion exchange. − …”

Eight new stable porous lanthanide metal–organic frameworks (Ln-OFs), namely, [Ln2(BPTC)2][(CH3)2NH2]2 [Ln = Ho (1), Eu (2), Gd (3), Dy (4), Er (5), Tm (6), Yb (7), Lu (8)], were prepared by 3,3′,5,5′-biphenyltetracarboxylic acid (H4BPTC) and lanthanide ions by solvothermal reactions. Complexes 1–8 show a three-dimensional (3D) 6,6-connected network {412·63}·{48·66·8} topology based on binuclear (Ln2) clusters and feature a one-dimensional curving porous channel occupied by exchangeable dimethylamine cations ([(CH3)2NH2]+) in the 3D anionic frameworks. The occupied [(CH3)2NH2]+ in the anionic channels exhibited excellent ion-exchange ability, which is favorable to Pd2+ and cationic dye adsorption. Consequently, 1–8 were used to load Pd nanoparticles to catalyze the reduction of nitrophenols and adsorb and desorb methyl blue (MB). The catalytic reaction efficiencies of Pd@1–8 were higher than that of Pd/C (5 wt %) in the hydrogenation reaction of p-nitrophenol (p-NP). Moreover, Pd@1 exhibited good cycle stability and achieved nearly 100% p-NP conversion after eight cycles. Meanwhile, compound 1 also exhibited a high adsorption ability of MB, possessing an adsorption capacity of 1.41 g·g–1 (second only to 1.49 g·g–1 reported in the literature) selectively over rhodamine B (RhB) and methyl orange (MO) in aqueous solutions. Remarkably, the skeleton of 1 remained stable after four adsorption–desorption cycles of MB in aqueous solution.

“…Besides mapping out mechanistic pathways, computational methods can help better understand this catalytic reaction in other ways. Zhang et al (2016), Sharma et al (2018) and Kong et al (2021) carried out DFT calculations to locate the most favorable binding sites of CO 2 in different MOFs as starting points of mechanistic investigations. Parmar et al (2019) performed grand canonical Monte Carlo (GCMC) simulations with MM force fields to obtain the sorption isotherm and binding sites of CO 2 in their Co-MOF, prior to DFT study on cycloaddition reaction pathway.…”

Catalytic conversion of the greenhouse gas CO2 into value-added chemicals and fuels is highly beneficial to the environment, the economy, and the global energy supply. Metal–organic frameworks (MOFs) are promising catalysts for this purpose due to their uniquely high structural and chemical tunability. In the catalyst discovery process, computational chemistry has emerged as an essential tool as it can not only aid in the interpretation of experimental observations but also provide atomistic-level insights into the catalytic mechanism. This Mini Review summarizes recent computational studies on MOF-catalyzed CO2 conversion through different types of reactions, discusses about the usage of various computational methods in those works, and provides a brief perspective of future works in this field.

As an aprotic O-donor ligand, 4,4′-bipyridine N,N′dioxide (DPO) shows good potential for the preparation of uranyl coordination compounds. In this work, by regulating reactant compositions and synthesis conditions, diverse coordination assembly between uranyl and DPO under different reaction conditions was achieved in the presence of other coexisting Odonors. A total of ten uranyl-DPO compounds, U-DPO-1 to U-DPO-10, have been synthesized by evaporation or hydro/ solvothermal treatment, and the possible competition and cooperation of DPO with other O-donors for the formation of these uranyl-DPO compounds are discussed. Starting with an aqueous solution of uranyl nitrate, it is found that an anionic nitrate or hydroxyl group is involved in the coordination sphere of uranyl in, and U-DPO-3 ((UO 2 )(DPO)(μ 2 -OH) 2 ), where DPO takes three different kinds of coordination modes, i.e. uncoordinated, monodentate, and biconnected. The utilization of UO 2 (CF 3 SO 3 ) 2 in acetonitrile, instead of an aqueous solution of uranyl nitrate, precludes the participation of nitrate and hydroxyl, and ensures the engagement of DPO ligands (4−5 DPO ligands for each uranyl) in a uranyl coordination sphere of U-DPO-4 ([(UO 2 )(CF 3 SO 3 )(DPO) 2 ](CF 3 SO 3 )), U-DPO-5 ([UO 2 (H 2 O)-(DPO) 2 ](CF 3 SO 3 ) 2 ) and U-DPO-6 ([(UO 2 )(DPO) 2.5 ](CF 3 SO 3 ) 2 ). Moreover, when combined with anionic carboxylate ligands, terephthalic acid (H 2 TPA), isophthalic acid (H 2 IPA), and succinic acid (H 2 SA), DPO works well with them to produce four mixedligand uranyl compounds with similar structures of two-dimensional (2D) networks or three-dimensional (3D) frameworks, U-DPO-7 ((UO 2 )(TPA)(DPO)), U-DPO-8 ((UO 2 ) 2 (DPO)(IPA) 2 •0.5H 2 O), U-DPO-9 ((UO 2 )(SA)(DPO)•H 2 O), and U-DPO-10 ((UO 2 ) 2 (μ 2 -OH)(SA) 1.5 (DPO)). Density functional theory (DFT) calculations conducted to probe the bonding features between uranyl ions and different O-donor ligands show that the bonding ability of DPO is better than that of anionic CF 3 SO 3 − , nitrate, and a neutral H 2 O molecule and comparable to that of an anionic carboxylate group. Characterization of physicochemical properties of U-DPO-7 and U-DPO-10 with high phase purity including infrared (IR) spectroscopy, thermogravimetric analysis (TGA), and luminescence properties is also provided.
