Although metal-organic framework (MOF) powders can be successfully shaped by conventional methods, postsynthetic functionalization of the shaped MOFs remains almost unexplored, yet is required to overcome intrinsic limitations, such as CO₂ adsorption capacity and stability. Here, we present a scalable synthesis method for Mg₂(dobpdc) MOF and its shaped beads, which are obtained by using a spray dry method after mixing Mg₂(dobpdc) powders with alumina sol. The synthesized MOF/Al beads have micron-sized diameters with a moderate particle size distribution of 30–70 μm. They also maintain a high mechanical strength. N-ethylethylenediamine (een) functionalization and coating with long alkyl chain silanes results in een-MOF/Al-Si, which exhibits a significant working capacity of >11 wt% CO₂ capture and high hydrophobicity. The een-MOF/Al-Si microbeads retain their crystallinity and improved CO₂ uptake upon exposure to humid conditions for three days at a desorption temperature of 140 °C.

尽管可以通过常规方法成功地成形金属有机骨架（MOF）粉末，但成形后的MOF的后合成功能化仍几乎未开发，但仍需要克服固有的局限性，例如CO ₂吸附能力和稳定性。在这里，我们提出了一种可扩展的Mg ₂（dobpdc）MOF及其异形珠的合成方法，这些方法是在混合Mg ₂之后通过喷雾干燥法获得的（dobpdc）粉末与氧化铝溶胶。合成的MOF / Al珠的直径为微米级，粒径分布中等，为30-70μm。它们还保持较高的机械强度。N-乙基乙二胺（een）官能化并用长烷基链硅烷进行涂覆会形成een-MOF / Al-Si，其具有大于11 wt％的CO ₂捕集率和较高的疏水性。een-MOF / Al-Si微珠在140°C的解吸温度下暴露于潮湿条件三天后，仍保持其结晶度并改善了CO ₂吸收。
