title: Nickel hydroxide nanoparticle activated semi-metallic TiO(2) nanotube arrays for non-enzymatic glucose sensing.
abstract: Semi-metallic TiO2 nanotube arrays (TiOx Cy NTs) have been decorated uniformly with Ni(OH)2 nanoparticles without the aid of a polymer binder. The resulting hybrid nanotube arrays exhibit excellent catalytic activity towards non-enzymatic glucose electro-oxidation. The anodic current density of the glucose oxidation is significantly improved compared with traditional TiO2 nanotubes decorated with Ni(OH)2 . Moreover, the Ni(OH)2 /TiOx Cy NT-based electrode shows a fast response, high sensitivity, wide linear range, good selectivity and stability towards glucose electro-oxidation, and thus provides a promising and cost-effective sensing platform for non-enzymatic glucose detection.
