英文摘要	zif-78 is a prototypical mixed-ligand compound among metal-organic frameworks (mofs), with the composition of divalent zinc cations bridging by 2-nitroimidazolate (nim) and 5-nitrobenzimidazolate (nbim) anions. zif-78 belongs to hexagonal space group (p6(3)/mmc) with a gme topology. owing to the anisotropic pore structure and good affinity to co2, zif-78 has potential applications in adsorption and separation fields. herein, morphological control of zif-78 crystals was achieved via solvothermal synthesis. xrd, sem, nmr, and adsorption characterizations were performed to study the crystalline phase, morphology, composition and adsorption behavior of obtained crystals, respectively. zif-78 micro-crystals with shape of the hexagonal rods were prepared with the assistance of triethylamine. the size and the aspect ratios of zif-78 microrods were manipulated from the "slender" to the "squat" via varying the nutrient concentration, the ligand concentration or relative molar ratio of nim to nbim.
