Abstract

One novel metal-organic framework {[Ni₆(OH)₄(BTB)_8/3(H₂O)₆]·4H₂O·9DMF} _n (DMF = dimethylformamide) based on 1,3,5-benzenetribenzoic acid (H₃BTB) was successfully synthesized under basic condition at room temperature, featuring a unique twofold interpenetrated pcu-type net with [Ni₆(OH)₄(COO)₈(H₂O)₆] cluster as building block. Its gas-adsorption behaviors were investigated and modified by utilizing metal^II-doped procedure, which was certified to be a highly effective pathway in enhancing CO₂ uptake capacity.
