High methane storage capacity in porous materials is important for the design and manufacture of vehicles powered by natural gas. Here, we report the synthesis, crystal structures and methane adsorption properties of five new zinc metal-organic frameworks (MOFs), MOF-905, MOF-905-Me2, MOF-905-Naph, MOF-905-NO2, and MOF-950. All these MOFs consist of the Zn4O(-CO2)6 secondary building units (SBUs) and benzene-1,3,5-tri-β-acrylate, BTAC. The permanent porosity of all five materials was confirmed, and their methane adsorption measured up to 80 bar to reveal that MOF-905 is among the best performing methane storage materials with a volumetric working capacity (desorption at 5 bar) of 203 cm(3) cm(-3) at 80 bar and 298 K, a value rivaling that of HKUST-1 (200 cm(3) cm(-3)), the benchmark compound for methane storage in MOFs. This study expands the scope of MOF materials with ultrahigh working capacity to include linkers having the common acrylate connectivity.
高甲烷存储容量的多孔材料是重要的设计和制造的车辆由天然气。在这里，我们报告了合成、晶体结构和甲烷吸附性能的五个新的锌金属-有机骨架(MOFs)，MOF-905、MOF-905-Me2、MOF-905-Naph、MOF-905-NO2 和 MOF-950。所有这些 MOFs 由 Zn4O(-CO2)6 二级建筑单元(SBUs)和苯-1,3,5-三-β-丙烯酸酯，BTAC。所有五种材料的永久孔隙率被证实，他们的甲烷吸附测量高达 80 巴揭示 MOF-905 是其中表现最好的甲烷存储材料之一，具有 203 厘米 3 厘米(-3)的体积工作能力(在 5 巴下解吸)在 80 巴和 298 K，这一值可与 MOFs 中甲烷存储的基准化合物 HKUST-1(200 cm 3 厘米(-3))相媲美。这项研究扩展了超高工作能力的 MOF 材料的范围，包括具有常见的丙烯酸盐连接性的连接体。
