该工作报告的原型金属有机框架（MOF-5）微晶的合成具有窄的尺寸分布，使用SiO2纳米粒子与定制的表面化学作为成核剂。与传统的M0 F-5溶剂热合成相比，纳米颗粒将反应速率提高了高达一个数量级，并且可以成功地用作在特定基底上选择性生长M0 F-5的成核种子。这些结果是朝着控制规模扩大MOF合成和在合适的支持物上定向生长MOF的重要基础性进展。
The work reports on the synthesis of an archetypal metal organic framework (MOF-5) microcrystals with a narrow size distribution using SiO2 nanoparticles with tailored surface chemistry as nucleating agents. The nanoparticles boost the reaction rate by up to an order of magnitude compared to the conventional MOF-5 solvothermal synthesis and can be successfully used as nucleation seeds for the selective growth of MOF-5 on specific substrates. These results are important fundamental advances toward the controlled scale-up of MOF synthesis and directed MOF growth on suitable supports.
