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

摘要

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 mu A.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. (C) 2017 Elsevier B.V. All rights reserved.
