摘要：

In this work, a peroxidase enzyme mimic is demonstrated using Mo-incorporated Cu@ZIF-8 and showed the electrochemical detection of hydrogen peroxide. Further, TMB, a chromogenic substrate, is introduced to enhance the kinetics and sensor performance of the resultant enzyme mimic. A significant gain in the overpotential value of 0.2 V and lower KM value is noted for the sensor upon introducing TMB. The characteristic kinetic parameters are determined, and a possible mechanism is elucidated for the proposed hydrogen peroxide sensor.
