英文摘要	The hydrogen storage properties of two pillared-layer metal-organic frameworks of Ni-2(BTEC)(bi-py)(3)center dot 3DMF center dot 2H(2)O (1) and Ni-2(BDC)(2)(dabco)center dot 4DMF center dot 1.5H(2)O (2) (BTEC = 1,2,4,5-benzenetetracarboxylate; bipy = 4,4'-bipydine; BDC = 1,4-benzenedicarboxylate; dabco = 1,4-diazabicyclo[2.2.2]octane; DMF = N,N'-dimethylformamide) were investigated. Compound 1 and 2 show a total hydrogen capacity of 1.78 and 3.96 wt.% at 77 K, respectively. Compound 2 exhibits a total hydrogen uptake of 0.81 wt.% at 299 K and 60 bar. At zero coverage, the heat of hydrogen adsorption of 1 and 2 is calculated to be 7.08 and 5.83 kJ/mol, respectively. The impacts of metal ions, pore structures, and surface areas on the hydrogen storage properties are discussed. Distorted aromatic pore structures introduced by multi-coordination ligands such as BTEC are proposed to be favorable to increase the hydrogen adsorption heats. The activated conditions and the stability in air of MOF samples are also concerned here. (C) 2010 Elsevier Inc. All rights reserved.
