A new MOF with high water stability and selective CO2 adsorption
A new MOF, {[Fe15(µ3-O)5(L4−)6(H2O)13(CH3COO)8]Cl3}n (SYU-3, SYU for Shenyang University, H4L = [1,1′:4′,1″-triphenyl]-3,3″,5,5″-tetracarboxylic acid), with (3,3,4,4,4,4,4,4,5,6,7)-connected nets, was synthesized via the combination of H4L with FeCl3·6H2O in N,N-dimethylformamide/acetic acid solvent system. Interestingly, SYU-3 is isomorphic to Quin-Fe-TPTC, which is a five-component MOF based on the same metal and ligand and possesses cages and channels in it. However, SYU-3 shows a different valence state of iron and was obtained by a one-step reaction without the need to prepare Fe–O clusters in advance. Moreover, SYU-3 exhibits high water stability, it also shows 10.4 wt% carbon dioxide adsorption amounts under 298 K and 1 bar and 84.7 adsorption selectivity of carbon dioxide to nitrogen. Grand canonical Monte Carlo simulations show that both cages and channels provide carbon dioxide binding sites, which may result in the selective carbon dioxide adsorption of SYU-3.
期刊介绍：
Transition Metal Chemistry is an international journal designed to deal with all aspects of the subject embodied in the title: the preparation of transition metal-based molecular compounds of all kinds (including complexes of the Group 12 elements), their structural, physical, kinetic, catalytic and biological properties, their use in chemical synthesis as well as their application in the widest context, their role in naturally occurring systems etc.
Manuscripts submitted to the journal should be of broad appeal to the readership and for this reason, papers which are confined to more specialised studies such as the measurement of solution phase equilibria or thermal decomposition studies, or papers which include extensive material on f-block elements, or papers dealing with non-molecular materials, will not normally be considered for publication. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures.
