摘要
Carboxylate-based metal–organic frameworks(CMOFs)have received considerable attentions for their high stability,catalytic activity,and porosity.However,synthesis of CMOFs requires high temperature,pressure,and long reaction time.Here,we explored the activity of 2-methylimidazole(2-MIM)for ultrafast synthesis of CMOF nanostructures(CMOFNs),in aqueous medium at room temperature and reaction time of 10 min.Seven CMOFNs have been synthesized by using Al3+,Cr3+,Cu2+,Fe3+,In3+,or Cd2+salt and1,4-bezenedicarboxylic acid,or 1,3,5-benzenetricarboxylic acid.Through this technique,the CMOFs with space time yield 181–501 kgcrystal sizes of ca.200–700 nm was obtained.
