Abstract

CuCo2O4 nanowire arrays supported on carbon cloth (CuCo2O4 NWAs/CC) were prepared via a simple hydrothermal synthesis and subsequent calcination process. As a 3D binder-free electrode for non-enzymatic glucose sensing, CuCo2O4 NWAs/CC shows high sensing performance towards glucose under alkaline conditions, with a wide detection range from 1 μM to 0.93 mM, a low detection limit of 0.5 μM (S/N = 3), and a high detection sensitivity of 3.93 mA mM−1 cm−2. Moreover, CuCo2O4 NWAs/CC shows good selectivity in the presence of common interferents and good reproducibility for glucose detection, which make it a promising electrode material for sensitive determination of glucose in human samples.
