摘　　要：由于C_(2)H_(2)和CO_(2)具有相似的物理化学性质,从C_(2)H_(2)/CO_(2)分离提纯出C_(2)H_(2)具有较大挑战。本研究利用较高极性的N/O原子嵌入孔表面的有效策略,在柱层式超微孔PCP,Co-datz-mipa(Hdatz=3,5-二氨基-1,2,4-三唑;H_(2)mipa=5-甲基-间苯二甲酸)中实现了高效的C_(2)H_(2)/CO_(2)分离。极性N/O原子能够与C_(2)H_(2)产生特异性识别。吸附等温线和穿透曲线表明了Co-datz-mipa能选择性吸附CO_(2)中的C_(2)H_(2)。The separation and purification of C_(2)H_(2) from C_(2)H_(2)/CO_(2) mixture is of great challenging due to their similar physical and chemical properties.In this study,a pillared-layer ultramicroporous coordination polymer with polar pore surface bearing with N/O atoms Co-datzmipa(Hdatz=3,5-diamino-1,2,4-triazole;H_(2) mipa=5-methyl-isophthalic acid)was used as an efficient adsorbent for C_(2)H_(2)/CO_(2) separation.Polar N/O atoms can form specific recognition with C_(2)H_(2).Adsorption isotherms and dynamic breakthrough curves show that Co-datz-mipa can adsorb C_(2)H_(2) selectively from CO_(2).
