A rare sty type microporous metalâorganic framework, Cu2(FDDI) (ZJU-25; H4FDDI = tetramethyl 5,5â²-(9H-fluorene-2,7-diyl)diisophthalate acid), was solvothermally synthesized and structurally characterized. With open metal sites and suitable pore space for their interactions with methane molecules, ZJU-25a exhibits absolute methane storage of 180 cm3(STP) cmâ3 at room temperature and 35 bar, enabling it to be one of the very few porous MOFs whose methane storage capacities have met and/or approached the DOE target of 180 cm3(STP) cmâ3 for material-based methane storage.
采用溶剂热法合成了一种稀有麦粒肿型微孔金属有机骨架 Cu2(FDDI)(ZJU-25;H4FDDI = 四甲基 5,5-(9H-芴-2,7-二基)二间苯二甲酸)并进行了结构表征。 ZJU-25a 具有开放的金属位点和适合与甲烷分子相互作用的孔隙空间,在室温和 35 bar 下表现出 180 cm3(STP) cm-3 的绝对甲烷储存量,使其成为极少数的多孔 MOF 之一其甲烷储存能力已达到和/或接近能源部基于材料的甲烷储存 180 cm3(STP) cm-3 的目标。
