The invention discloses applications of a
cobalt complex as a
greenhouse gas adsorption material. The molecular formula of the
cobalt complex is {[Co<3>(H<3>TTHA)<2>(4, 4'-bipy)<5>(H<2>O)<8>*12H<2>O]}<n>, wherein H<3>TTHA is used for representing ligand 1, 3, 5-
triazine-2, 4, 6-triamine-hexaacetate (H6TTHA) lost three protons, and 4, 4'-bipy is used for representing 4, 4'-dipyridyl molecules. Thecobalt complex possesses excellent adsorption performance on water vapour and CO2, the structure can be maintained to be stable at
high humidity environment, recycling can be realized, and the cobaltcomplex is an excellent
greenhouse gas adsorption material.
