据报道，三维多孔金属有机骨架[Cu(SiF6)(4,4 ' -bpy)2]具有较高的甲烷储存量。关于[Cu(SiF6)(4,4 ' -bpy)2]的研究仅与甲烷储存有关，而详细的合成、表征和[Cu(SiF6)(4,4 ' -bpy)2]的吸附性能，特别是H2和CO2的吸附性能的研究很少。本文通过调整试剂的摩尔比、合成温度和结晶时间，合成了[Cu(SiF6)(4,4′-bpy)2]。此方法在低温下获得[Cu(SiF6)(4,4′-bpy)2]，此前未见报道。温度对样品的合成起着重要的作用，低温有利于合成较大的样品。测定了二氧化碳和氢气在高压下的吸附等温线。[Cu(SiF6)(4,4’-bpy)2]在18 bar条件下H2储存量高达2.36 wt%，在298 K条件下CO2捕获量高达4.17 mmol g−1。
A 3-D porous metal–organic framework [Cu(SiF6)(4,4′-bpy)2] was reported to have high methane storage. The studies about [Cu(SiF6)(4,4′-bpy)2] were only related with methane storage but information on detailed synthesis and characterization as well as adsorption properties of [Cu(SiF6)(4,4′-bpy)2], especially the H2 and CO2 adsorption properties, was scarce. In this work, [Cu(SiF6)(4,4′-bpy)2] has been synthesized by adjusting the molar ratio of the reagents, synthesis temperature, and crystallization time. This method for obtaining [Cu(SiF6)(4,4′-bpy)2] at low temperature has not been reported before. Temperature played an important role in synthesis of the sample and low temperature was beneficial for synthesizing bigger sample. Adsorption isotherms for carbon dioxide and hydrogen were measured under high pressure. [Cu(SiF6)(4,4′-bpy)2] exhibited H2 storage up to 2.36 wt% at 18 bar and a high CO2 capture up to 4.17 mmol g−1 at 298 K at 10 bar.
