We developed a facile and general method to synthesize various HP-MOFs such as HKUST-1, ZIF-8, ZIF-61, and ZIF-90 within 1 min at room temperature and ambient pressure, using organic amines as protonation-templating agents. The morphology and porosity of hierarchically porous HKUST-1 can be readily tuned by varying the type of organic amines or the synthesis time. The space–time yield reached as high as 4.05 × 10⁴ kg m⁻³ d⁻¹, at least 1 order of magnitude higher than previously reported values. In addition, the mechanism for rapid HP-MOF synthesis was elucidated for the first time by using a simulation technique. This strategy provides a new method for the facile, quick and large-scale synthesis of various HP-MOFs for a wide range of applications.

具有高时空产率的分层多孔金属有机框架的超快速室温合成

我们开发了一种简便且通用的方法，使用有机胺作为质子模板剂，可以在室温和环境压力下1分钟内合成各种HP-MOF，例如HKUST-1，ZIF-8，ZIF-61和ZIF-90。可以通过改变有机胺的类型或合成时间来容易地调节分级多孔的HKUST-1的形态和孔隙率。时空产量高达4.05×10 ⁴ kg m ^-3 d ^-1，比以前报道的值至少高出一个数量级。此外，首次通过模拟技术阐明了快速HP-MOF合成的机理。该策略为各种应用提供了一种简便，快速，大规模合成各种HP-MOF的新方法。
