The solvent-free mechanical milling process for two distinct metal-organic framework (MOF) crystals induced the formation of a solid solution, which is not feasible by conventional solution-based syntheses. X-ray and STEM-EDX studies revealed that performing mechanical milling under an Ar atmosphere promotes the high diffusivity of each metal ion in an amorphous solid matrix; the amorphous state turns into the porous crystalline structure by vapor exposure treatment to form a new phase of a MOF solid solution.
无溶剂机械球磨工艺可用于两种不同的金属-有机骨架（MOF）晶体，从而诱导形成固溶体，而这在传统的基于溶液的合成中是不可行的。X 射线和 STEM-EDX 研究表明，在 Ar 气氛下进行机械球磨可促进每个金属离子在非晶固体基质中的高扩散性；非晶态通过蒸气暴露处理转变为多孔结晶结构，从而形成 MOF 固溶体的新相。
