We report here the first example of ZIF materials synthesized in aqueous solution. The synthesis was performed at room temperature and typically took several minutes compared to hours and days in non-aqueous conditions. The obtained product were ZIF-8 nanocrystals having size of ~85 nm and showed excellent thermal, hydrothermal and solvothermal stabilities.
A hierarchical zeolitic imidazolate framework-8 (micro/meso-ZIF-8) was fabricated by using cetyltrimethylammonium bromide as a structure-controlling agent and l-histidine as co-templates. Compared to the conventional microporous ZIF-8 (micro-ZIF-8), the hierarchical porous structure of micro/meso-ZIF-8 contains micropores and maximum mesopores of around 35.6 nm. The as-prepared hierarchical mic...
