Processing powdered metal–organic frameworks (MOFs) into more usable forms can greatly expand their practical applications. We report a very simple and efficient method for synthesizing a green-friendly γ-cyclodextrin (CD)-MOF monolith (rather than powder), without using any connectors or high temperature/pressure. Compared with the γ-CD-MOF-powder, the γ-CD-MOF-monolith showed much better humidity stability because the MOF particles in the γ-CD-MOF-monolith were tightly packed. In addition, the CO₂ adsorption test indicated that it had a higher volume adsorption capacity for CO₂, with adsorption capacities of 44.04 and 36.85 cm³/cm³ at 0 and 25°C, respectively. The γ-CD-MOF-monolith can maintain its porous structure and gas adsorption capacity even after 14 days of exposure to humid conditions, and the amount of CO₂ absorption remains almost unchanged. This humidity stable γ-CD-MOF-monolith is expected to have greater practical applications than its powdered counterpart in many applications including CO₂ adsorption.

用于 CO2 捕集的湿度稳定的绿色 γ-环糊精金属-有机骨架整体材料的简便制备

将粉末金属有机框架（MOF）加工成更可用的形式可以极大地扩展其实际应用。我们报告了一种非常简单有效的合成绿色 γ-环糊精 (CD)-MOF 整体材料（而不是粉末）的方法，无需使用任何连接器或高温/高压。与γ-CD-MOF-粉末相比，γ-CD-MOF-整体显示出更好的湿度稳定性，因为γ-CD-MOF-整体中的MOF颗粒紧密堆积。此外，CO ₂吸附试验表明，它对CO 2 具有较高的体积吸附容量_，吸附容量分别为44.04和36.85 cm ³ /cm ³分别在 0 和 25°C。γ-CD-MOF-整体材料即使在潮湿条件下暴露14天后仍能保持其多孔结构和气体吸附能力，CO ₂吸附量几乎保持不变。_{这种湿度稳定的γ-CD-MOF-整体料在包括CO 2}吸附在内的许多应用中比其粉末对应物具有更大的实际应用。
