The synthesis and structure of Co(2)(ad)(2)(CO(2)CH(3))(2) x 2 DMF x 0.5 H(2)O (bio-MOF-11) is described. Pyrimidine and amino groups of adeninate (ad) decorate the pores of the framework. The porosity of this material was studied, and its CO(2) and H(2) adsorption properties were evaluated. bio-MOF-11 exhibits a high heat of adsorption for CO(2) (approximately 45 kJ/mol), a high CO(2) capacity (approximately 6 mmol/g, 273 K), and exceptional selectivity for CO(2) over N(2) at 273 K (81:1) and 298 K (75:1).
介绍了 Co(2)(ad)(2)(CO(2)CH(3))(2) x 2 DMF x 0.5 H(2)O（bio-MOF-11）的合成与结构。腺嘌呤（ad）的嘧啶和氨基基团修饰了骨架的孔道。研究了该材料的多孔性，并评估了其 CO(2)和 H(2)吸附性能。bio-MOF-11 对 CO(2)的吸附热较高（约 45 kJ/mol），CO(2)容量较高（约 6 mmol/g，273 K），在 273 K（81:1）和 298 K（75:1）时对 CO(2)相对于 N(2)具有出色的选择性。
