Rapid Room-Temperature Synthesis and Characterization of Nanocrystals of a Prototypical Zeolitic Imidazolate Framework

The rapid room-temperature synthesis and characterization of Nanocrystals of a Prototypical Zeolitic Imidazolate Framework (ZIF) material has been reported. Comparison of an X-ray diffraction (XRD) pattern taken from a powder sample with a pattern simulated from structure demonstrates that the product is single-phase ZIF-8 material. The mixing, microwave, ultrasound, and microemulsion methods have been used for synthesis and achieving some degree of size and shape. Such preformed nanocrystals should be excellent candidates for the preparation of supported ZIF films and membranes, as known for zeolites. nanoscale microporous adsorbents and catalysts are favorable over microscale ones with regard to the mass and energy transport properties. method of excess protic linker might be a general one and transferable to other ZIFs, and even carboxylate-based MOFs at low pH conditions.
