摘要

在这项工作中，利用 Mo-incorporated Cu@ZIF-8 演示了一种过氧化物酶模拟物，并展示了过氧化氢的电化学检测。此外，为了提高酶模拟物的动力学和传感器性能，还引入了发色底物 TMB。引入 TMB 后，传感器的过电位值明显提高了 0.2 V，KM 值也降低了。确定了特征动力学参数，并阐明了拟议的过氧化氢传感器的可能机理。

Mo-Incorporated Bimetallic Metal–Organic Framework for Electrochemical Detection of Hydrogen Peroxide: A Potential Biomimic System

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 K_M 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.

期刊介绍： Electrocatalysis is cross-disciplinary in nature, and attracts the interest of chemists, physicists, biochemists, surface and materials scientists, and engineers. Electrocatalysis provides the unique international forum solely dedicated to the exchange of novel ideas in electrocatalysis for academic, government, and industrial researchers. Quick publication of new results, concepts, and inventions made involving Electrocatalysis stimulates scientific discoveries and breakthroughs, promotes the scientific and engineering concepts that are critical to the development of novel electrochemical technologies. Electrocatalysis publishes original submissions in the form of letters, research papers, review articles, book reviews, and educational papers. Letters are preliminary reports that communicate new and important findings. Regular research papers are complete reports of new results, and their analysis and discussion. Review articles critically and constructively examine development in areas of electrocatalysis that are of broad interest and importance. Educational papers discuss important concepts whose understanding is vital to advances in theoretical and experimental aspects of electrochemical reactions.
