Abstract :
A novel composite electrode composed of ordered TiO2 nanotube arrays and carbon nanoparticles was fabricated by thermal chemical reaction of butanone and anodized TiO2 nanotube arrays on Ti sheet. This composite electrode exhibits favorable voltammetric responses to K3Fe(CN)6 and dopamine. The linear responsive range of dopamine is 1.0×10-6 to 1.0×10-4 M and the detection limit of dopamine is 8.0×10-8 M (S/N=3).
