Selectively catalytic micro- and nanocrystals of metal–organic framework [Co(4-bpdh)(HIA)]{sub ∝}
Metal–organic framework micro-crystals [Co(4-bpdh)(HIA)]{sub ∝} (1Co), crystallized in the monoclinic system (space group P12/n1, a=10.0009(16) Å, b=15.472(3) Å, c=18.563(3) Å, β=91.81(0)°, and Z=4), were controllably synthesized through the adjustment of the solvent system. The Co{sup 2+} ion center located in a six-coordinated environment combined with 5-hydroxyisophthalic acid (HIA) to produce ladder-like structures, which again linked with 2,5-bis(4-pyridyl)-3,4-diaza-2,4-hxadiene (4-bpdh) to yield a double-layer network. Micro-crystals 1Co exhibited selectively oxidation-catalytic properties for the degradation of methyl orange (conversion 90%) owing to ligand to metal charge transfer. Our work determined that the synthesized catalyst is not only highly selective for degradation of organic dyes, but also very efficient. - Graphical abstract: Metal–organic framework micro-crystals [Co(4-bpdh)(HIA)]{sub ∝} (1Co) were controllably synthesized through the adjustment of the solvent system.
