摘要：Metal-organic framework micro-crystals [Co(4-bpdh)(HIA)](proportional to) (1Co), crystallized in the monoclinic system (space group P12/n1, a =10.0009(16) angstrom, b=15.472(3) angstrom, c= 18.563(3) angstrom, beta=91.81(0)degrees, and Z=4), were controllably synthesized through the adjustment of the solvent system. The Co2+ 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-pyridy1)-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. (C) 2014 Elsevier Inc. All rights reserved.
