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 and 1,4-bezenedicarboxylic acid,or 1,3,5-benzenetricarboxylic acid,Through this technique,the CMOFs with space time yield 181-501 kg m-3 day 1 and crystal sizes of ca.200-700 nm was obtained.
