Abstract

A nickel hydroxide (Ni(OH)₂)/3D-graphene composite is used as monolithic free-standing electrode for enzymeless electrochemical detection of glucose. Ni(OH)₂ nanoflakes are synthesized by using a simple solution growth procedure on 3D-graphene foam which was grown by chemical vapor deposition (CVD). The pore structure of 3D-graphene allows easy access to glucose with high surface area, which leads to glucose detection with an ultrahigh sensitivity of 3.49mAmM^-1cm^-2 and a significant lower detection limit up to 24nM. Cyclic voltammetry (CV) and potentionstatic mode is used for non-enzymatic glucose sensing. The impedance and effective surface area have been studied well. The high sensitivity, low detection limit and simple configuration of Ni(OH)₂/three dimensional (3D)-graphene composite electrodes can evoke its industrial application in glucose sensing devices.
