In this work, a metal‐organic frameworks‐based porous carbon was explored for glucose oxidase immobilization and glucose sensing. ZIF‐67 was chosen as the precursors for the calcination treatment. The formed Co nanoparticles induced the graphitization of the carbon during the carbonization, resulting in a good conductivity. The followed HCl treatment partly removed the formed Co nanoparticles to give a larger specific surface area of the porous carbon due to the generated space voids from the dissolved Co nanoparticles. The resulting MOFs‐derived porous carbon show an improved loading performance toward glucose oxidase, and fast electron transfer was also demonstrated. This work proves the MOFs‐derived porous carbon as a novel and outstanding platform for the enzymatic electrocatalysis for the sensors and energy conversion devices.

ZIF-67源自煅烧和酸蚀过程中的多孔碳，可作为酶固定平台进行葡萄糖感测。

在这项工作中，探索了一种基于金属-有机骨架的多孔碳，用于葡萄糖氧化酶的固定和葡萄糖感测。选择ZIF-67作为煅烧处理的前体。所形成的Co纳米颗粒在碳化期间引起碳的石墨化，从而导致良好的导电性。由于从溶解的Co纳米颗粒产生的空间空隙，随后的HCl处理部分地去除了形成的Co纳米颗粒，以提供较大的多孔碳比表面积。所得的源自MOFs的多孔碳对葡萄糖氧化酶的负载性能有所改善，并且还证明了快速的电子转移。这项工作证明了MOF衍生的多孔碳是用于传感器和能量转换设备的酶促电催化的一种新颖而出色的平台。
