It is highly desirable to design enzyme‐free nanoarray architecture as an efficient three‐dimensional (3D) catalyst electrode for sensitive and selective detection of glucose. In this communication, we report that in situ electrochemical development of an amorphous cobalt‐borate nanoarray supported on carbon cloth (Co–Bi /CC) as a durable and efficient 3D nanoarray electrocatalyst for glucose detection. As a glucose sensor, Co−Bi/CC electrode shows a fast amperometric response toward glucose, a detection limit of 0.042 μM (S/N=3), a response sensitivity of 4191.7 μA mM⁻¹ cm⁻². Importantly, it also demonstrates favourable reproducibility and long‐term stability.

3D非晶硼酸钴纳米阵列的原位形成：用于非酶葡萄糖检测的高效非贵金属催化电极

非常需要将无酶纳米阵列结构设计为有效的三维（3D）催化剂电极，用于灵敏和选择性地检测葡萄糖。在本次交流中，我们报道了碳布（Co–Bi / CC）上负载的无定形钴硼酸盐纳米阵列的原位电化学开发，它是一种耐用，高效的葡萄糖检测3D纳米阵列电催化剂。作为葡萄糖传感器，Co-Bi / CC电极显示出对葡萄糖的快速安培响应，0.042μM（S / N = 3）的检测极限，4191.7μAmM ^-1 cm ^-2的响应灵敏度。重要的是，它还显示出良好的重现性和长期稳定性。
