Abstract

A tailored metal-organic framework transducer material Cu−BDC(NH2)@2-MI was synthesized with 2-methylimidazole as competitive ligand for the modulation of its morphology and catalytic activity. 2-MI effectively helped the deprotonation of 2-aminoterephthalic acid and enabled the fast generation of MOF crystals at room temperature. More importantly, this 2-MI-doped MOF exhibited well-tuned morphology and was able to assist efficient redox procedures in electrochemical H2O2 reduction. Therefore, a prototype H2O2 sensor can present decent linear ranges from 10 μM to 13.28 mM and a detection limit of 0.97 μM. This novel design could boost the utilization of proprietary MOFs materials out of laboratory.
