A Ni3N–Co3N hybrid nanowire array electrode for high-performance nonenzymatic glucose detection

Abstract

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.
