Facile synthesis of Ni(OH)2 nanowires on nickel foam via one step low-temperature hydrothermal route for non-enzymatic glucose sensor

Ni(OH)2 nanowires were successfully fabricated on nickel foam via one step low-temperature hydrothermal route without nickel salts added. The results revealed that the prepared Ni(OH)2 nanowires with average diameter of about 200 nm are arranged on porous sponge-shape nickel foam. The Ni(OH)2 nanowires modified Nickel foam electrode can be used as non-enzymatic glucose sensor with a high sensitivity of 1598 µA·mM−1·cm−2, a linear range covering from 0.1 mM to 6 mM and a short response time within 3 s at an applied bias of 0.55 V vs. Ag/AgCl. Furthermore, The Ni(OH)2 nanowires modified nickel foam electrode exhibited a good ability of selectivity and stability.
