“…These images also indicate that the size of ZIF-67 ranged from 0.1 to 1.0 lm. Although the formation of ZIF was resulted from the chemical bonding between the metal ion and the ligand, the selection of salts for the metal ion can directly affect the size of ZIF (Shao et al, 2014). Since the cobalt metal ion used in this study was from cobalt nitrate, the resulting ZIF was expected to be the middle-size ZIF (i.e., <1.0 lm), which agreed with the observational size of ZIF-67 in Fig.…”

“…Zeolitic imidazole framework-67 was synthesized according to the reported procedure with modification (Shao et al, 2014). In a typical synthesis, 4 mmol of Co(NO 3 ) 2 Á6H 2 O was first dissolved in 100 mL of methanol, while 16 mmol of 2-MIM was added to another glass vial containing 100 mL of methanol.…”

“…For example, Jiang et al [16] have synthesized ZnS hollow polyhedron with Zncontaining ZIF-8. Shao and co-workers [17] have synthesized Co 3 O 4 hollow dodecahedrons with ZIF-67. Therefore, ZIFs are an ideal self-template to synthesize hollow nanostructures without auxiliary template.…”

“…Co-based ZIF-67 was prepared using a protocol reported previously [16]. In detail, 0.024 mol of cobalt nitrate hexahydrate and 0.048 mol of 2-methylimidazole were dissolved in 300 mL of methanol, respectively.…”

“…In recent years, the control of the porous structure via pyrolysis has attracted increasing research efforts. For instance, Shao et al reported that the hollow Co 3 O 4 dodecahedrons, which exhibit promising application in Li storage, could be obtained through direct pyrolysis of Co-based zeolitic imidazolate frameworks (ZIF-67) [16]. The synthesis of Fe 2 O 3 with mesoporous structure composed of nanoparticles was also achieved by the pyrolysis of Fe-based metalorganic framework (MOF) for high-performance Li batteries [17].…”
