Extensive research has been devoted to developing new porous materials with high methane storage capacity. While great progress has been made in recent years, it still remains very challenging to target simultaneously high gravimetric and volumetric methane (CH ) working capacities (deliverable amount between 5.8 and 65 bar) in a single material. Here, a novel metal-organic framework (termed as UTSA-110a) constructed by an extended linker containing a high density of functional nitrogen sites, exhibiting both very high gravimetric and volumetric working capacities of 317 cm (STP: 273.15 K, 1 atm) g and 190 cm (STP) cm , respectively, for robust MOFs, is reported. Both of these values are higher than those of two benchmark materials: HKUST-1 (207 cm (STP) g or 183 cm (STP) cm ) and UTSA-76a (267 cm (STP) g or 187 cm (STP) cm ). Computational studies reveal that it is the combination of optimized porosity and favorable binding sites that leads to the simultaneously high gravimetric and volumetric working capacities in this material.
研究人员致力于开发具有高甲烷存储容量的新型多孔材料。尽管近年来取得了重大进展，但在单一材料中同时实现高重量和体积甲烷（CH ）工作容量（5.8 至 65 巴之间的输送量）仍然极具挑战性。在这里，报告了一种由含有高密度功能氮位的扩展配体构建的新型金属有机骨架（称为 UTSA-110a），其具有非常高的重量和体积工作容量，分别为 317 cm （STP：273.15 K，1 atm） g 和 190 cm （STP） cm ，对于坚固的 MOFs 来说，这两个值都高于两个基准材料：HKUST-1（207 cm （STP） g 或 183 cm （STP） cm ）和 UTSA-76a（267 cm （STP） g 或 187 cm （STP） cm ）。计算研究表明，正是优化的孔隙率和有利的结合位点的结合导致了该材料中同时具有高重量和体积工作容量。
