Abstract
The present invention provides a method for the adsorptive separation of CHand CHusing ultramicroporous metal-organic framework material, comprising the following steps that (1) CH/CHmixture is contacted with the ultramicroporous metal-organic framework material; (2) CHis preferentially adsorbed and the separation of CH/CHis realized. The described 'ultramicroporous metal-organic framework material' has a formula of [MLA], wherein M represents the metal cation being any one of Cu, Zn, Co, and Ni; L represents the organic linker being any one of 1,2,4-triazole and its derivatives; A represents the oxygen-containing inorganic anion being any one of POand VO. The class of ultramicroporous metal-organic frameworks has optimal pore size and pore chemistry, exhibiting both higher uptake capacity and faster adsorption rate for CHas compared to CH, thus CHcan be preferentially adsorbed by these metal-organic frameworks with high selectivity, and high-purity CHcan be separated from CH/CHmixtures efficiently.
