Abstract

Nanosized metal–organic frameworks (nano-MOFs) have shown significant potential across diverse fields, while the challenge of achieving energy- and time-efficient scaling-up synthesis hampers their practical applications. This work presents a cost-effective colloid-milling method that enforces nucleation–growth separation during crystallization for the scalable synthesis of nano-MOFs under ambient conditions. Compared to the static method, the colloid-milling method not only greatly improves the production efficiency by 2 orders of magnitude but also produces smaller nano-MOFs with narrower size distribution that exhibit higher catalytic activity than the larger-sized ones. This work offers a promising option for the large-scale production of nano-MOFs.

胶体磨强制成核-生长分离技术用于放大合成纳米级金属有机框架

纳米级金属有机框架（nano-MOFs）已在多个领域展现出巨大的潜力，但实现高能效和高时效的放大合成所面临的挑战阻碍了其实际应用。本研究提出了一种经济有效的胶体研磨方法，该方法可在结晶过程中实现成核-生长分离，从而在环境条件下实现纳米金属有机框架的规模化合成。与静态法相比，胶体研磨法不仅将生产效率大大提高了两个数量级，而且生产出的纳米 MOFs 尺寸更小，粒度分布更窄，比大尺寸的 MOFs 表现出更高的催化活性。这项工作为大规模生产纳米 MOFs 提供了一种可行的选择。
