Preparation of zinc oxide nanoparticles from nanoporous metal-organic framework with one-dimensional channels occupied with guest water molecules

摘要

A new nanoporous metal-organic framework Zn-2(NDC)(2)(DMF)(2)(H2O)(4) (1 center dot DMF center dot H2O) [H2NDC = 2,6-naphthalene dicarboxylic acid and DMF = N,N'-dimethylformamide], with guest water molecules has been synthesized and characterized. This MOF is made up of a stacked arrangement of four-connected layers. Stacked arrangement of layers results in formation of nanoporous channels. The thermal stabilities of 1 center dot DMF center dot H2O and 1 center dot DMF were studied by TGA (thermo gravimetric analyses). The host and the apohost frameworks of 1 center dot DMF center dot H2O, 1 center dot DMF and 1 were used for preparation of ZnO nanomaterials. With calcination of the host framework of 1 center dot DMF center dot H2O, ZnO nanoparticles can be fabricated. By the same process on the apohost frameworks of 1 center dot DMF and 1, agglomerated nanoparticles of ZnO were formed. (C) 2015 Elsevier B.V. All rights reserved.
