The paddle-wheel type cluster Co2(RCOO)4(LT)2 (R = substituent group, LT terminal ligand), possessing unusual metal coordination geometry compared with other cobalt compounds, may display high catalytic activity but is highly unstable especially in water. Here, we show that judicious considerations of the host/guest geometries and modular synthetic strategies, labile dicobalt clusters can be immobilized stabilized a metal-organic framework (MOF) as coordinative guests. Fe(na)4(LT) fragment...
Abstract Two‐dimensional (2D) materials and ultrathin nanosheets are advantageous for elevating the catalysis performance elucidating mechanism of heterogeneous catalysts, but they mostly restricted to inorganic or organic based on covalent bonds. We report an electrochemical/chemical exfoliation strategy synthesizing metal–organic 2D coordination A catechol functionalized ligand is used as redox active pillar construct a pillared‐layer framework. When 3D MOF serves electrocatalyst water...
Framework flexibility is one of the most important characteristics metal–organic frameworks (MOFs), which not only interesting, but also useful for a variety applications. Designing, tailoring or controlling framework MOFs much more difficult than static structural features such as topology and pore size/shape. Nevertheless, with in-depth understanding relationship between host structure, guest loading other aspects crystal size/morphology external physical environment, some strategies have...
Using a bis-triazolate ligand and tetrahedral Zn(II) ion, we synthesized flexible porous coordination polymer functionalized with pairs of uncoordinated triazolate N-donors that can be used as guest chelating sites to give very high CO2 adsorption enthalpy CO2/N2 selectivity. The dynamic sorption behavior could monitored well by single-crystal X-ray diffraction.
Reversible chemisorption of CO<sub>2</sub>is realized by introducing monodentate hydroxide onto the pore surface metal–organic frameworks.
Cu-based metal-organic frameworks have attracted much attention for electrocatalytic CO2 reduction, but they are generally instable and difficult to control the product selectivity. We report flexible Cu(I) triazolate as efficient, stable, tunable electrocatalysts reduction C2 H4 /CH4 . By changing size of ligand side groups, selectivity ratio can be gradually tuned inversed from 11.8 : 1 2.6, giving , CH4 hydrocarbon selectivities up 51 %, 56 77 respectively. After long-term...
Chemical separations, mostly based on heat-driven techniques such as distillation, account for a large portion of the world's energy consumption. In principle, differential adsorption is more energy-efficient separation method, but conventional adsorbent materials are still not effective many industry-relevant mixtures. Porous coordination polymers (PCPs), or metal-organic frameworks (MOFs), attractive their well-defined, designable, modifiable, and flexible structures connecting to various...
Abstract Much effort has been devoted to develop new porous structures for methane storage. We report a coordination framework showing exceptional uptakes (e.g. 263 v / at 298 K and 65 bar) adsorption enthalpies (21.6 kJ mol −1 ) as high current record holders functionalized by open metal sites. Computational simulations demonstrated that the hierarchical pore structure consisting of single‐wall nanocages suitable sizes/shapes organic binding sites enforce not only strong host–methane...
Abstract Efficient adsorptive separation of propylene/propane (C 3 H 6 /C 8 ) is highly desired and challenging. Known strategies focus on either the thermodynamic or kinetic mechanism. Here, we report an interesting reactivity a metal–organic framework that improves adsorption selectivity simultaneously. When heated under oxygen flow, half soft methylene bridges organic ligands are selectively oxidized to form more polar rigid carbonyl bridges. Mixture breakthrough experiments showed...
Abstract Cobalt imidazolate frameworks are classical electrocatalysts for the oxygen evolution reaction (OER) but suffer from relatively low activity. Here, a non‐3d metal modulation strategy is presented enhancing OER activity of cobalt frameworks. Two isomorphous [Co 4 (MO )(eim) 6 ] (M=Mo or W, Heim=2‐ethylimidazole) having Co(eim) 3 ) units and high water stabilities were designed synthesized. In different neutral media, Mo‐modulated framework coated on glassy carbon electrode shows best...
