A new three-dimensional (3D) framework, [Ni(btzip)(H btzip)]⋅2 DMF⋅2 H O (1) (H btzip=4,6-bis(triazol-1-yl)isophthalic acid) as an acidic heterogeneous catalyst was constructed by the reaction of nickel wire and a triazolyl-carboxyl linker. Framework 1 possesses intersected 2D channels decorated by free COOH groups and uncoordinated triazolyl N atoms, leading to not only high CO and C H adsorption capacity but also significant selective capture for CO and C H over CH and CO in 273-333 K. Moreover, 1 reveals chemical stability toward water. Grand Canonical Monte Carlo simulations confirmed the multiple CO - and C H -philic sites. As a result of the presence of accessible Brønsted acidic COOH groups in the channels, the activated framework demonstrates highly efficient catalytic activity in the cycloaddition reaction of CO with propylene oxide/4-chloromethyl-1,3-dioxolan-2-one/3-butoxy-1,2-epoxypropane into cyclic carbonates.

A Zn-MOF was constructed by a F-decorated ligand and bipyridyl linkers, displaying selective adsorption for CO2, C2H6, C2H2 over CH4, catalysis for CO2 conversion and selective adsorption for methyl blue.
