Tekin, A.Karalti, O.Karadas, F.2018-04-122018-04-1220161387-1811http://hdl.handle.net/11693/36810A new microporous metal dicyanamide cluster, Co(hmt)(dca)2 (hmt: hexamethylenetetramine, dca: dicyanamide), with accessible N-donor sites exhibits high CO2/N2 selectivity, 83 at 295 K and 1 bar, for a mixture with a 15:85 CO2 to N2 ratio. Adsorption studies show that the use of hmt and dca moieties as building blocks for solid adsorbents can enhance the CO2:surface interactions due to N atoms available inside the pores, which is confirmed by X-ray single crystal studies.EnglishAdsorptionCO2 adsorptionCO2/N2 selectivityCrystal structureDicyanamideArticle10.1016/j.micromeso.2016.03.0351873-3093
