Abstract

This research was to prepare the titanium dioxide nanotube arrays (TiNT arrays) and deposit the Au nanoparticles on its surface using the pulse electrodeposition technique. The Au nanoparticles-TiNT arrays (AuNP-TiNT arrays) were characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction, and cyclic voltammetry. The results showed that the Au nanoparticles were uniformly dispersed on the TiNT array surface. The size and loading of Au nanoparticles can be controlled by deposition time, deposition potential, and concentration of HAuCl 4 . The AuNP-TiNT arrays were then used as a working electrode for hydrogen peroxide (H 2 O 2 ) detection. Compared with the pure TiNT array electrode, the AuNP-TiNT array electrode had higher sensitivity for the detection of H 2 O 2 and thus provided a simple, promising, and cost-effective sensing platform for the development of enzyme-based biosensors. © The Japan Society for Analytical Chemistry.
