机械化学为直接从金属氧化物中制备金属有机骨架Zn-MOF-74提供了一种快速、有效的途径，无需散装溶剂。原位同步x射线衍射监测的反应过程揭示了两个新的阶段和一个不寻常的逐步过程，其中一个封闭的中间反应形成开放的框架。该反应可以在克尺度上进行，在活化后产生高度多孔的材料。
Mechanochemistry provides a rapid, efficient route to metal organic framework Zn-MOF-74 directly from a metal oxide and without bulk solvent. In situ synchrotron X-ray diffraction monitoring of the reaction course reveals two new phases and an unusual stepwise process in which a close-packed intermediate reacts to form the open framework. The reaction can be performed on a gram scale to yield a highly porous material after activation.
