Mesoporous ZnO(-COO)-based metal-organic frameworks (MOFs), including UMCM-1, MOF-205, MUF-7a, and the newly synthesized MOFs, termed ST-1, ST-2, ST-3, and ST-4 (ST = ShanghaiTech University), have been systematically investigated for ultrahigh capacity methane storage. Exceptionally, ST-2 was found to have the highest deliverable capacity of 289 cm/cm (567 mg/g) at 298 K and 5-200 bar, which surpasses all previously reported records held by porous materials. We illustrate that the fine-tuned mesoporosity is critical in further improving the deliverable capacities at ultrahigh pressure.
基于中孔 ZnO(-COO)的金属-有机骨架（MOFs），包括 UMCM-1、MOF-205、MUF-7a 以及新合成的 MOFs，称为 ST-1、ST-2、ST-3 和 ST-4（ST = 上海科技大学），已被系统地研究用于超高容量甲烷储存。特别地，发现 ST-2 在 298 K 和 5-200 bar 下具有最高的可输送容量 289 cm/cm（567 mg/g），超过了所有先前报道的多孔材料的记录。我们表明，精细调节的中孔率对于进一步提高超高压力下的可输送容量至关重要。
