Textured and house-of-card structures develop on the surfaces of cubic MOF-5 crystals. The formation mechanism of these novel constructions are investigated based on characterisation of the intermediate specimens with different reaction time intervals using scanning and transmission electron microscopies. It is found that the growth of MOF-5 cubic crystals does not follow the classical route. MOF-5 nanocrystallites initially aggregate to form large polycrystalline cubes, followed by surface rearrangement of the nanocrystallites into a textured structure consisting of nanowires lying along the [100], [010], [110] and [110] zone axes, if the face of the cube is defined to be (001). Further crystal growth leads to a house-of-cards structure constructed by interpenetrated nanoplates with their shortest axis parallel to [110] and [110] axes. Evidence of a reversed crystal growth process is also observed. MOF-5 cubes with a single crystal-like appearance are achieved with extended reaction times despite their hidden three tier structure containing varying porosities hidden underneath.

“…Additionally, the thermal stability of HKUST-1 was determined by TGA, finding the structure is decomposed at 337 º C. The HKUST-1 sample exhibited a continuous mass loss of 20.1 %, up to a temperature of 100 °C due to the loss of ethanol and water. After decomposition, at 336.9 °C, 23.5 % of the starting weight remains, and this residual material could correspond to the formation of copper oxides, metallic copper or residual carbon [32]. The HKUST-1 synthesized by stirring at room temperature generates a 3D structure with BET and Langmuir specific surface area of 1345.9 and 1637.6 m 2 g -1 , respectively.…”

“…the phase purity of ZIF-8 increased with the increase in reaction time and remained unchanged after 50 minutes, whereas the crystal size of ZIF-8 increased with the increase in reaction time. The research results Biemmi et al (2009) [7] have shown the evolution of the HKUST-1 structure as a function of temperature despite the formation of metal oxide Cu2O phase at a temperature of 453 K. In addition, the regularity of morphology of the HKUST-1 crystals decreased with the increase in reaction temperatures. In the case of MOF-5 synthesis, Choi et al (2008) [13] have investigated the effect of reaction time on crystallinity of MOF -5 synthesized by use of microwave method at various reaction time of 15, 30, 45 and 60 min.…”

AbstractMOF-5 (metal-organic frameworks-5) have been synthesized using solvotermal method in which reaction mixtures of zinc nitrate hexahydrate and benzenedicarboxylic acid in dimethylformamide were heated at various heating temperatures and times in order to obtain the best reaction conditions for the synthesis of MOF-5. The heating temperatures used were 105, 120 and 140 °C, respectively with heating times of 12-144 hours. Determination of the best reaction conditions was based on the observation of phase purity and crystal morphology of MOF-5 using XRD and SEM. The characterization results showed that optimization of MOF-5 crystals were obtained when the reaction mixtures were heated at 105 °C for 144 h, 120 °C for 24 h and 140 °C for 12 h. The maximum weight of MOF-5 crystal was generated from reaction mixture heated at 120 °C for 72 h.
