The rational design and development of efficient and affordable enzyme‐free electrocatalysts for electrochemical detection are of great significance for the large‐scale applications of sensor materials, and have aroused increasing research interest. Herein, we report that a typical polyoxometalate (POM)‐based metal–organic framework (NENU5) that was hybridized with ketjenblack (KB) was a highly efficient electrochemical catalyst that could be used for the highly sensitive nonenzymatic detection of H2O2. The composite catalyst exhibited superb electrochemical detection performance towards H2O2, including a broad linear range from 10–50 mm, a low detection limit of 1.03 μm, and a high sensitivity of 33.77 μA mm−1, as well as excellent selectivity and stability. These excellent electrocatalytic properties should be attributed to the unique redox activity of the POM, the high specific surface area of the metal–organic framework (MOF), the strong conductivity of KB, and the synergistic effects of the multiple components in the composites during the electrolysis of H2O2. This work provides a new pathway for the exploration of nonenzymatic electrochemical sensors.

基于多金属氧酸盐的金属有机框架与科琴黑的杂化用于 H2O2 的非酶检测
合理设计和开发高效、经济的电化学检测用无酶电催化剂对于传感器材料的大规模应用具有重要意义，并引起了越来越多的研究兴趣。在此，我们报道了一种典型的基于多金属氧酸盐（POM）的金属有机框架（NENU5）与ketjenblack（KB）的杂化是一种高效的电化学催化剂，可用于H 2 O 2的高灵敏度非酶检测。该复合催化剂对H 2 O 2表现出优异的电化学检测性能，包括10~50 mm m的宽线性范围、1.03 μm的低检测限和33.77 μA mm −1的高灵敏度，以及优异的选择性和稳定性。这些优异的电催化性能应归功于POM独特的氧化还原活性、金属有机骨架（MOF）的高比表面积、KB的强导电性以及复合材料中多种组分在催化过程中的协同效应。 H 2 O 2电解。这项工作为探索非酶电化学传感器提供了新途径。
