In this communication, we report a new type of nickel cobalt nitride hybrid nanowire array in situ grown on a Ti plate (Ni₃N–Co₃N NW/Ti) topotactically converted from Ni–Co hydroxide as a high activity catalyst electrode for glucose electrooxidation in alkaline media. As a non-enzymatic glucose sensor, such a Ni₃N–Co₃N NW/Ti electrode exhibits superior electrochemical sensing performance with a short response time of less than 5 s, a wide detection range of 0.1 μM to 4.0 mM, a low detection limit of 30 nM (S/N = 3), and a high sensitivity of 4418.7 μA mM⁻¹ cm⁻², as well as satisfactory selectivity and reproducibility. Furthermore, it also performs efficiently for glucose detection in human blood serum, indicating that this novel electrode is a promising candidate for nonenzymatic glucose sensing.

用于高性能非酶葡萄糖检测的 Ni ₃ N–Co ₃ N杂化纳米线阵列电极†

在本次交流中，我们报告了一种在Ti板上原位生长的新型镍钴氮化物杂化纳米线阵列（Ni ₃ N–Co ₃ N NW / Ti），从Ni–Co氢氧化物转变成高活性的葡萄糖催化电极在碱性介质中发生电氧化。作为一种非酶葡萄糖传感器，这种Ni ₃ N–Co ₃ N NW / Ti电极具有出色的电化学传感性能，响应时间短于5 s，检测范围从0.1μM到4.0 mM，低。检测极限为30 nM（S / N = 3），高灵敏度为4418.7μAmM ^-1 cm ^-2以及令人满意的选择性和重现性。此外，它还可以有效地检测人血清中的葡萄糖，表明该新型电极是非酶促葡萄糖传感的有前途的候选者。
